%%%Occured in Blender 2.63.0 r45996
Windows XP 32-bit SP3 EN
ATI Radeon HD 2600 Pro, driver version 8.950.0.0

Create cube (or use cube in default startup scene)
Add Multiresolution modifier
Press "Subdivide" on modifier settings panel 8-9 times
Press ctrl+z to undo several times
Repeat again until crashes (usually crashes at first undo but sometimes undo works to state of 0 subdivides, but after doing subdivide again and undoing again crashes)

Output of gdb (using standard binaries without debug symbols so not so many information):

Program received signal SIGSEGV, Segmentation fault.

%%%Sounds like this isn't multires related. Judging from "0xbaadf00d", I guess uninitialized mem, impossible to say where from this backtrace.

Submitter: is this using the official 2.63 build? Have you tried 2.63a?%%%

%%%Yes, later discovered it was occuring not only by using multires.
Yes, occured in official build. And it not occuring in 2.63.0 for Mac OS, however it is r46461 (windows 2.63.0 is r45996).
I will try 2.63a.

%%%One last thing to try, can you see if a more recent build works? Graphicall has some: http://graphicall.org/32bit/windows

Reassigning to Elubie.%%%

%%%Tried 2.63.11 r48011, this build http://graphicall.org/170
Windows XP 32-bit SP3 (the same configuration as in issue description).

Crash not occurs in this build, tried subsurf and undo multiple times, also tried adding cylinder and setting radius that caused crash in previous versions.%%%
