Short description of error
If you sculpt an object with multires modifier and these object shares mesh with other witch have multires too blender fall down
Exact steps for others to reproduce the error

this does not happen with all the brushes but with the majority

Can't reproduce here with latest master, no crash.

Graphics card: GeForce GTX 750 Ti/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 384.130
(Only weird thing I noticed was that nothing happens when you undo/redo individual sculpts steps with instanced multires objects - only see changes when you undo/redo a mode switch. Wonder if that's worth a report?)

As already asked, does this happen with the latest blender build?
