Are you building your own blender with WITH_OPENSUBDIV_MODIFIER?
(seems to be working there, cant reproduce crash)

Also cannot reproduce a crash on the current buildbot build (multiresolution modifier there seems pretty much useless though because you cannot see the subdivided mesh in sculptmode?)

Anyways, this is still WIP, so while not 100% identical, will merge into T56508 and leave for @Sergey Sharybin (sergey) to greenlight the Opensubdiv modifier...
