Short description of error
Adjusting primitives causes crashes.

Exact steps for others to reproduce the error
I am getting lots of crashes when adding and adjusting primitives. Sometimes just adding a UV Sphere will instantly crash, but if not, this seems to crash every time:

Here is what the Win10 stacktrace looks like when using a debug build (and executing: bpy.ops.mesh.primitive_uv_sphere_add(segments=12, ring_count=6, radius=0.25))

Seems to confirm a problem in the bmo_remove_doubles_exec -> BLI_kdtree_free code path

Exception thrown at 0x00007FF8659448AE (ntdll.dll) in blender.exe: 0xC0000005: Access violation reading location 0xFFFFFFFFFFFFFFFF.
