Hello all,
Is anyone else seeing a crash on exit with OSG applications (even
osgviewer and the examples) under MS VS8.0 when running in the debugger?
To be specific:
* Running in Visual Studio 8.0SP1
* Debug configuration
* Mike's 3rd Party binaries for VS 8.0SP1
Repro steps: run osgviewer with cow.osg as argument (in debug properties).
A) If you just do some things and exit, no crash on exit.
B) If you press 's' (or I guess any other text - anything that will
load osgdb_freetyped.dll to be loaded), and then exit, crash.
Running from the command line does not show any problem. I need to be
in the debugger for it to show up.
The actual message I get is:
_______________________________________________
HEAP[osgviewerd.exe]: HEAP: Free Heap block 1d01268 modified at

Windows has triggered a breakpoint in osgviewerd.exe.
This may be due to a corruption of the heap, and indicates a bug in
osgviewerd.exe or any of the DLLs it has loaded.

________________________________________________
The last code I can inspect is in msvcr80d.dll!_free_base(void *
pBlock). The last relevant OSG call is
osgdb_freetyped.dll!_FT_New_Memory() called by
osgdb_freetyped.dll!_ft_mem_free(). But I can't inspect that code.
I think I'll try to compile a local version of FreeType and see if
it's a problem with the version that's in Mike's binaries.
In the mean time, can anyone please try to reproduce this? (see above)
Thanks,
J-S
