Unfortunately a backtrace is not very useful for such memory
corruption problems.
Similarly to the dreaded "triangleintersect" message, this is only
triggered way after the event when some system (namely glibc or OSG)
detects the problem. By that time, it is too late to figure anything
out. To make things worse, such errors don't tend to be reproducible.

[Flightgear-devel] fgfs crash after about 1 hour 15 min

2011-01-22 Thread dave perry 
With yesterday's git for fgfs and simgear, after about 1.25 hours,
fgfs froze and I had to use System Monitor to end process fgfs.

All seemed normal up to the freeze.

OS, up-to-date FC14 on an I7 desktop with nvidia GeForce GTX 260, NVIDIA 
driver Version: 260.19.29.

Command line (from fgrun wizard):

/usr/local/bin/fgfs
   --fg-root=/home/dad/source-osg/fgdata
   
--fg-scenery=/home/dad/source-osg/fgdata/Scenery:/home/dad/source-osg/TerraSync
   --airport=KLWB
   --aircraft=pa24-250-CIIB
   --control=joystick
   --disable-random-objects
   --enable-ai-models
   --enable-real-weather-fetch
   --prop:/sim/frame-rate-throttle-hz=30
   --prop:/sim/menubar/autovisibility/enabled=1
   --geometry=1680x1050
   --visibility-miles=30
   --bpp=32
   --fov=65
   --texture-filtering=16
   --atlas=socket,out,5,localhost,5505,udp
   --atlas=socket,out,5,localhost,5500,udp
   --prop:/sim/rendering/shader-effects=true
   --nav1=109.5
   --nav2=114.2
   --adf=400
   --dme=nav1

I had just passed Casanova VOR (116.3 CSN) on the 72 deg radial (approx. 
7 nm out bound).

Here is the backtrace:
