Bug#763821: [pkg-fgfs-crew] Bug#763821: FlightGear can't load any data and gets Segmentation fault

2014-10-05 Thread Bo Lan 
Please do not close it right now, because I experienced another crash
with Segmentation Fault when I do a long distance flight from VHHH to
RJGG.

Here is the information, including gdb:

First of all, I used this command to start the fgfs:

$ OSG_LIBRARY_PATH=/usr/lib/x86_64-linux-gnu fgfs
--fg-root=/usr/share/games/flightgear
--fg-scenery=/usr/share/games/flightgear/Scenery
--fg-aircraft=/home/qs/flightgear-aircraft --airport=VHHH --runway=25L
--aircraft=A330-243 --control=joystick --enable-random-objects
--enable-horizon-effect --enable-enhanced-lighting --disable-ai-models
--disable-ai-traffic --enable-real-weather-fetch --enable-clouds3d
--prop:/sim/rendering/texture-compression=off
--prop:/sim/frame-rate-throttle-hz=60
--prop:/sim/menubar/autovisibility/enabled=1 --bpp=32
--timeofday=morning --enable-terrasync --disable-fgcom

After about half an hour of flying, it crashed with segmentation fault.
Then I used gdb to backtrack:

$ OSG_LIBRARY_PATH=/usr/lib/x86_64-linux-gnu gdb fgfs

(gdb) run --fg-root=/usr/share/games/flightgear
--fg-scenery=/usr/share/games/flightgear/Scenery
--fg-aircraft=/home/qs/flightgear-aircraft --airport=VHHH --runway=25L
--aircraft=A330-243 --control=joystick --enable-random-objects
--enable-horizon-effect --enable-enhanced-lighting --disable-ai-models
--disable-ai-traffic --enable-real-weather-fetch --enable-clouds3d
--prop:/sim/rendering/texture-compression=off
--prop:/sim/frame-rate-throttle-hz=60
--prop:/sim/menubar/autovisibility/enabled=1 --bpp=32
--timeofday=morning --enable-terrasync --disable-fgcom

Then it crashed, and this is the backtrack:

Bug#763821: [pkg-fgfs-crew] Bug#763821: FlightGear can't load any data and gets Segmentation fault

2014-10-04 Thread Rebecca Palmer 
The underlying bug has now been fixed in unstable, and this fix should 
reach testing in 5-10 days; you can either use the environment variable 
workaround until then, or install the fixed libopenscenegraph100 from 
unstable ( 
https://www.debian.org/doc/manuals/debian-reference/ch02.en.html#_tracking_literal_testing_literal_with_some_packages_from_literal_unstable_literal 
).


Are the unable to load messages gone as well?  If so, I agree that 
this bug should be closed.

Bug#763821: [pkg-fgfs-crew] Bug#763821: FlightGear can't load any data and gets Segmentation fault

2014-10-03 Thread Rebecca Palmer 

Please install the debugging symbols and run a backtrace, as follows:

$ sudo apt-get install libsimgearcore3.0.0-dbg libsimgearscene3.0.0-dbg gdb
$ gdb fgfs
(gdb) run
[wait for crash]
(gdb) thread apply all bt full

Is it possible that you're running out of memory?  Given that you have 
TerraSync enabled (which is higher resolution than the built-in 
scenery), expect to use around 2.5GB.


The 'not found' errors suggest an incomplete Terrasync download (terrain 
but not the objects that go with it), but I don't know if they're 
related to the crash; does

$ fgfs --disable-terrasync
load successfully?  If it does, try turning Terrasync back on via the 
tick box under File  Scenery Download and waiting for it to finish 
(~200MB, Information shows status), then closing and restarting FlightGear.

2014-10-03 Thread Bo Lan 
Hi,

Thank you for your reply.

Yes, after disable the terrasync, it would not crash anymore. The crash
is possibly related to the terrasync, but it is impossible caused by
running out of memory. This computer has 8gb memory.

The most importantly, the objects still cannot be loaded.

Here is the debug backtrack information:

Hi,

  experiencing similar problem, it looks to be related to the bug in
libopenscenegraph100:

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=763816

(temporary fix: OSG_LIBRARY_PATH=/usr/lib/x86_64-linux-gnu/ works for me)

Cheers,
Pavel
