[Bf-committers] Blender (CVS) crashing on loading a .blend file

[Erwin Coumans]

Hi,

Someone posted a .blend file created with Blender 2.41 but it crashes with 
latest Blender 2.42.
I might be my visual studio 8 build, but can someone else verify this?

It crashes in LOD_Vertex::RemoveEdge

This is the file that causes the crash (it's 2.5 Mb zipfile)
http://www.continuousphysics.com/ftp/pub/test/index.php?dir=blender/&file=Open%20the%20Door.zip

Could someone look into this? Below is the stackframe at crash.
Thanks,
Erwin
