Hi,
My git build here recently started crashing on exit again. I've been
looking into it and I think I traced it to
simgear/environment/visual_enviro.cxx in the destructor around line #190.
This module builds up sound effects for thunder/lighting, in a "weather"
sample group. The module keeps a pointer to the sample group and then tries
to delete it in the destructor.
But i suspect that the sound manager is getting destructed first and the
sample group is already removed, so the pointer in visual_enviro.cxx is just
hanging out there still pointing to garbage ... so when we call the
destructor on it, we blow up.
The destructor has an "if (ptr == NULL)" type check, but obviously this does
nothing if something external deletes the object, and the module's pointer
never knows the difference so it is still non-null.
Anyway, would it be safe to remove this call to delete in the
visual_enviro.cxx destructor and depend on the sound manager destructor to
clean it up? Or should we try to do something fancier?
Thanks,
Curt.
