**Short description of error**
Sculpting on a multires object will cause Blender to lock up while applying a stroke (when using a very recent build). There's no crash, Blender just freezes indefinitely.
**Exact steps for others to reproduce the error**
Open the .blend file and start sculpting on the object, Blender will lock up before you even finish the first stroke. The root cause of this may also be causing a bug where it's not possible to open a .blend file containing a multires object (Blender will lock up instead).
