I don't know why an exception would not be caught, since  
E3TriMesh_OptimizeData has a catch (...) block.  However I do see why  
there was no exception in the debug build.  E3Memory_AllocateClear is  
asked to allocate a block of size 0, but due to the debugging header  
and trailer, the call to calloc actually allocates a nonzero sized  
block.  Whereas in the release build, E3Memory_AllocateClear will  
return NULL.

I agree with the change you made to  
TriMeshOptimizer::BuildEdgeAttributes.
