Ok, I was a bit early with the conclusion that this is Cuda related.
Seems not. The only tests that pass are:
- rtkappsimulatedgeometrytest
- rtkappprojectshepploganphantomtest
- rtkwaveletstest
- rtkargsinfomanagertest
Kind regards

Hi,
Thanks for the report. Seems like something is happening in the ITK
code. Are other non cuda tests failing?
Did you also compile ITK with C++11? BTW, why is it required?
Best regards,
Simon

Hello,
I was able to build RTK using Cuda 9 on an Arch Linux machine with
gcc 6.4 with only small modifications:
#=========================================================

In addition I had to set CMAKE_CXX_FLAGS to -std=gnu++11 manually in
the ccmake dialog (unfortunately I was not able to integrate this in
the top-level CMakeLists so far, CMake simply ignored it there..).
So far, so good. Unfortunately all Cuda tests fail with the same
segfault. For example, rtkimportcudatest finishes with
****** Case 1: unsigned short ******

Segmentation fault (core dumped)
To further investigate what is going wrong here, I ran valgrind. I
think the most important message is this:

I've put the full log here: https://pastebin.com/CBjJmUpB
Does someone have any idea, what is going wrong here?
Thanks for any help!
