Hi, I found kind of a hint of the cause of DList stack overflow.
After reset, the number of ssgTransform increases a lot. so maybe this has something to do with the cause of the problem since ssgTransform::cull calls _ssgPushMatrix and _ssgPopMatrix. these two show "DList stack overflow" error. Plus, this problem doesn't happen when --disable-ai-models is specified. When I commented out <scenario>nimitz_demo</scenario> from preferences.xml, this DL stack overflow doesn't happen even without --disable-ai-models. So resetting carrier object in AICarrier::init() or methods called from init() probably generates redundant or unexpected ssgTransform objects. I'll dive deeper tomorrow. If any of you have any idea on what causes this, please let me know.
