That does not relate to the subsurface modifier. The crash can be reproduced with other generate-modifiers as well.

Seems to go wrong when updating the normals during the release of the sculpt/paint bvh. There were recently some changes there for sculpting. Will bisect to see when this started.

It seems like it wants to update normals in a case when bvh->mpoly and bvh->mloop are not correct. vertex indexes they point to have indexes of USHORT_MAX and UINT_MAX.

The data seems to be correct, but gets incorrect along the way...
