[Bf-committers] modifier stack bug report-

[Campbell Barton]

Hi Danial, heres another one I found when playing with teh mirror tool.

To Reproduce...

    Make a UV-Sphere with default settings.
    Delete half of the verts on the x/y/z axis so you and up with an 8th
    of a sphere.
    Add 3 Mirrors to the modifier stack. X/y/z so you have a compleate
    sphere again.
    Add Subsurf to the modifier to the stack
    Go in and out of edit mode-

Heres the backtrace.
