Hi, 

On the last test I made I used the source code cloned from 
https://phabricator.mitk.org/source/mitk.git today (after you merged the patch 
into the master), with no modification nor additional code. 

I proceeded to the following build steps: 
- Switched on MITK_USE_SOFA in the superbuild (which forced 3 boost libraries 
on), configured twice, generated the solution, and built project ALL_BUILD in 
debug mode 
- Switched in CMake to the MITK-build directory to switch both 
MITK_BUILD_org.mitk.simulation and MITK_BUILD_org.mitk.gui.qt.simulation 
plugins on, configured and generated. 
- I opened the solution directly from CMake, then built and run MITKWorkbench. 

All projects are built successfully (including MitkWorkbench without any error, 
but I encounter an error when running MitkWorkbench (in Debug mode). I also 
tried to use the /BlueBerry.clean argument, with the same result. 

When I run MitkWorkbench, a pop-up window appears with the following text: 
-------------------------------------------------------------------------------------------------------------------------
 
Exception thrown: read access violation. 
this-> was 0x7FFF33F669E8 
If there is a handler for this exception, the program may be safely continued. 
-------------------------------------------------------------------------------------------------------------------------
 

I encounter the error before the interface is visible, and it occurs when the 
plugins are being loaded. Here is the call stack when the application crashes:

The code crashes when a call is made to method insertArchive in 
ctkPluginStorageSQL.cpp, relatively to the simulation plugin. This triggers a 
call to QPluginLoader::unload() method, and finally results in a crash when 
calling release() method of a Boost smart pointer. 

I'll keep investigating but at the moment I don't know why this happens. 

I certainly can provide you with more details if you need some. 

Best, 


Camille

Hi, I tested successfully on Windows 10 as well. I need more information to be 
able to guess what's going on. Did you modify or add code? What's the call 
stack? Does it work by simply start the Workbench with a /BlueBerry.clean 
argument? When does it crash? 


Best, 

Stefan

Hi 

Thanks for your messages, and for the patch. I had encountered the MSVC related 
error you mentionned before (snprintf, hash_map, and eigen) but hadn't gone 
further. 

However I think that the first problem I mentioned with this topic is not 
related to the compiler version, nor to these problems. 
I've just tried to compile (with MSVC 2015) and execute MITK with the patch you 
merged earlier today into master, and although the building process is now 
performed successfully, I still encounter the same error (memory access 
violation) when trying to execute the Workbench. 

In addition to that, a colleague of mine successfully reproduced this problem 
on another computer with the following configuration: 
- Windows 10 (version 1607, anniversary update) 
- CMake v3.5.2 
- Qt v5.6.2 
- MITK 2016.11.0 release sources 
- MSVC 2013 Community Update 5 

You mentioned that you tested several configurations today: did one of these 
include a Windows 10 environment? 

Best, 

Camille

Hi, 


I just gave it a shot with MSVC 2015 and pushed a branch for this[1]. Seems 
like it is working now but it needs more testing.

Hi Stefan, Camille, 

The issues are not OS related but compiler related. VS 2015 has issues with 
snprintf. Once you solve them you (there's a macro to disable that check) you 
will find issues with the private eigen version of SOFA. Those issues are much 
harder to solve. 

If you use Vs 2013 you won't find these issues.

Hi, 



it was Windows 8.1. Regarding Windows 10, we only have configurations with 
VS2015, but not VS2013. We found some compile errors regarding snprintf on 
these machines today, which I will investigate later today or tomorrow. 



Best, 

Stefan

Hi, 

As a follow-up to my previous mail, here is what I could give a deeper look to: 

- I started the building process from the beginning on another computer with 
the same configuration, except for the OS which was Microsoft Windows 7 
(service pack 1, x64). I didn't encounter the same error and was able to 
successfully launch the Workbench with the simulation plugin on. 
- I tried to suppress everything related to MITK on the computer running under 
Windows 10 and started once more, in case there would have been a conflict I 
would not have been aware of. Once again I was able to go through all the 
building process without any error, but encountered the same problem (memory 
access violation) when running the Workbench. 
- I finally updated my Windows 10 version with the anniversary update (version 
1607, build 14393), but this was also unsuccessful. 

Considering these elements I would say the problem is likely to come either 
from windows 10 or from conflicting files on my computer I couldn't find. 

Were you running on Windows 10 when you tried to reproduce the error? Or do you 
know if a test has been made recently on Windows 10 (I saw it was part of the 
Tier 2 supported platforms)? 
Otherwise the problem must be specifically related to something on my computer. 

Regards, 

Camille

Hi Stefan, 

Thanks for your answer! 

I did exactly the same as you described in the first two lines of your message 
(and encountered the same forced switch on for the Boost libraries). 

As for the things that could have gone wrong: 

- I didn't encounter any error during the superbuild (although warnings were 
triggered), and everything was built successfully 
- I used the debug batch file (StartVS_debug.bat) to launch the Workbench after 
compiling in Debug mode. I also tried to do all the building process in Release 
mode (also following the same steps as you described), using this time the 
release batch file, and apparently encountered what seems to be the same error. 
- I checked that both simulation plugins (org.mitk.simulation and 
org.gui.qt.simulation) were indeed switched on 

I finally tried to delete all the Workbench folders in the AppData directory 
but I still encounter the same error, although not with the same callstack as 
plugins were directly loaded (and not updated). However a call to the 
insertArchive method is also made during this loading process, and it triggers 
the error when used relatively to the org.mitk.simulation plugin. 

I made a lot of manipulations relatively to MITK lately, and I'm not sure that 
I'm not missing anything. I'll try to reproduce the problem in a "clean" 
machine, starting from 2016.03 sources only, and going through the entire 
building process. 

I'll keep you updated if I encounter the error once more. 

Best, 

Camille

Hi, 



I have just done a superbuild with your setup (2016.03, CMake 3.7, VS 2013 
Community Update 5, and Qt 5.4.2). I switched on MITK_USE_SOFA in the 
superbuild. Boost with a few libraries were force switched on then. I 
configured again and generated the superbuild solution. I built the project 
MITK-Configure in Debug Configuration, and then switched in CMake to the 
MITK-build directory to switch on the two simulation plugins. 
Configure/Gerenrate. I used the debug batch file (!) to open the MITK solution 
and built/run MITKWorkbench. So everything works for me. 



Thing that might have gone wrong in your case: 



- Did you check, that the superbuild was completely successful? 

- Did you use the right batch file to open the MITK solution? 

- Did you switch on both simulation plugins? 

- If you’re sure that everything was built successfully, you can either go to 
%APP_DATA%/../Local/DKFZ and delete all the Workbench folders to force a clean 
start of the Workbench, or pass /BlueBerry.clean once as argument to the 
Workbench, which will do the same (remember to remove the argument later). You 
can add the argument in the properties of the MITKWorkbench project 
(Configuration Properties -> Debugging -> Command Arguments). 



Best 

Stefan

Hello everyone, 

I encounter an execution error (memory access violation) when trying to launch 
MITK Workbench with the simulation plugin. 

This error seems to result from a call to the insertArchive method of 
ctkPluginStorageSQL (relatively to org.mitk.simulation plugin), through the 
updateDB method. However I have difficulties to trace back the exact cause of 
the problem through the plugin loading process. 

Has this situation been encountered before? 

I leave more information concerning the error and my environment below. 

Best regards, 

Camille
