%%%Blender crashes while rotating two vertices in edit mode. It seems to be the edge split modifier. See the attached .blend. Enter edit mode (two verts should be selected. Rotate them, and Blender crashes for me. Turn off the edge split modifier, and the crash stops.

Running Blender 2.60.0 r41226 64-bit on Windows 7 64-bit.%%%

%%%Probably error is how vertices count is calculated (can see "Attempted to add a SmoothMesh vert beyond end of array" on the console). Will check if it's failure of modifier itself or it's something else produced this error.%%%

%%%Crash was fixed in rev41720, but actual problem still present in code. From commit log:

This bug is caused by exactly the same reason as #26316: differences in how new vertices/edges are getting calculated first and how they're adding later. In some cases extra vertices are creating which weren't counted before.

This patch prevents crash in such situations, but result mesh can be a bit wrong. This should work fine in bmesh, so think it's acceptable to have such workaround before actual fix coming with bmesh.

Thanks for report, closing it now.%%%
