Very nice !

Quite a nasty, stealth bug...

It is due to LLTexLayerSetBuffer being still LLRefCounted, instead of LLThreadSafeRefCounted like it now should be, given all texture classes have been changed to be thread-safe ref-counted, due to how GL textures can be created in shared OpenGL threads...

Fixed for next release. If you compile the viewer yourself, simply change line 44 of linden/indra/llappearance/lltexlayer.h to read:
Code:
class LLTexLayerSetBuffer : public virtual LLThreadSafeRefCount


Thanks for the report (and crash dump, which got me right to the point) !
