I have now debugged the problem a bit, and it does indeed manifest itself under
both Win32 debug and release builds. The root of the problem is that the static
s_renderBinPrototypeList object (osgUtil/RenderBin.cpp line 44) is being
created before the static s_ReferencedGlobalMutext object (osg/Referenced.cpp
line 82). Static/global objects are destructed in the reverse order of their
creation. This causes a problem when destructing s_renderBinPrototypeList,
since it depends on the already destructed s_ReferencedGlobalMutext object for
its destruction.
Suggested fix:
Modify Referenced::getGlobalReferencedMutex(), so that it forces
s_ReferencedGlobalMutext to be created in advance of s_ReferencedGlobalMutext.
--
OpenThreads::Mutex* Referenced::getGlobalReferencedMutex()
{
// make sure that s_ReferencedGlobalMutext is created in advance,
// since s_ReferencedGlobalMutext depend on it for its destruction
osg::Referenced::getGlobalReferencedMutex();
static OpenThreads::Mutex s_ReferencedGlobalMutext;
return &s_ReferencedGlobalMutext;
}
