System Information
Debian Stretch, AMD64 AVX, no AVX2, mesa r600g

Blender Version
Broken: current git master
Worked: 2.78c

Short description of error
Blender freezes on Edge Split or Rip (V-Key) with this non-manifold mesh and the selected Edge.
The selected edge is the one that causes the freeze.
The other non-manifold edge doesn't cause the freeze.
(Maybe there is some out-of-bound reads)

Exact steps for others to reproduce the error
Here is the .blend file:
Edge_split_bug.blend

Blender showed failure in several asserts before entering in the infinite loop!

There is really something very wrong there.
