System Information
Operating system and graphics card win7 gtx 550ti

Blender Version
Broken: (example: 2.69.7 4b206af, see splash screen) My own build and somehow i don't have the hash :( , I built it less than an hour ago
Worked: (optional)

Short description of error
Crash after sculpting first and adding more subdivision.

Exact steps for others to reproduce the error
Based on a (as simple as possible) attached .blend file with minimum amount of steps

Make sure that you have a build that was built WITH_OPENSUBDIV_MODIFIER ON otherwise you will not notice the crash
with the default cube go to sculpt mode
add multires. modifier and add some subdivisions, 2 will be okay
sculpt some, any brush will do.
add more subdivisions ( one will be good to crash Blender)

Another way to crash it
repeat a every step from above but the last one do this:
5. Delete the multres modifier while in sculpt mode.

PS: i know @Sergey is working on multires. that why i was a bit hesitating to fill a bug report. If it is a known issue feel free to close the report.

Can confirm (as of 0c8aa85069)

this is backtrace for the first way to crash (add more subdivisions)

this is from the second way to crash (delete modifier)
