System Information
Kubuntu Linux 14.04 64bits, nvidia GTX 960

Blender Version
Broken: 2.77 1f386cc
blender-2.77-1f386cc-linux-glibc219-x86_64 from buildbot

Short description of error
In this scene:
http://www.pasteall.org/blend/41015

I have a mesh in Layer 1 and another mesh in Layer 2. Layer 2 mesh has Shrinwrap and Multires modifiers. If I subdivide the edge that is possible to see as selected in edit mode, then Blender crash. Reproducible all the time.

Exact steps for others to reproduce the error
Open the scene. Press W key and select "Subdivide".

Can confirm here with latest head on Linux, segfault appears to be in BMesh.
