Description

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

  1. Make sure that you have a build that was built WITH_OPENSUBDIV_MODIFIER ON otherwise you will not notice the crash
  2. with the default cube go to sculpt mode
  3. add multires. modifier and add some subdivisions, 2 will be okay
  4. sculpt some, any brush will do.
  5. 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:

  1. Delete the multres modifier while in sculpt mode.

PS: i know @Sergey Sharybin (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 rB0c8aa85069fabd20d5f030f016a85ad060839066)

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