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).
