Hi,
I'm new to OpenSceneGraph and not sure if I get everything right. I get crashes
with Visual Studio 2005 static build after the main function returns. The crash
occurs while the static s_renderBinPrototypeList is destructed.
While debugging, I have found something suspicious: There are two RegisterRenderBinProxy instances
in RenderBin.cpp, one with the name "RenderBin" and one with "DepthSortedBin".
They both add the corresponding entries to the s_renderBinPrototypeList correctly before main()
enters.
However, the s_registerDepthSortedBinProxy removes the wrong entry in s_renderBinPrototypeList
afterwards. This happens because the proxy class calls removeRenderBinPrototype which uses
proto->className to find the entry to erase from the s_renderBinPrototypeList map. Remember that the
destructor of s_registerDepthSortedBinProxy should remove the "DepthSortedBin" entry.
Unfortunately, proto->className equals "RenderBin" in both cases.
When s_registerRenderBinProxy tries to delete the "RenderBin" entry later, it
fails because it is already deleted. Then, s_renderBinPrototypeList still contains the
DepthSortedBin entry which was never deleted.
What OSG version are you using?
