Running a debug build: the crash happens in
blender/source/blender/blenkernel/intern/customdata.c:4037
in the functionCustomData_bmesh_interp_n
, becausesub_weights
isNULL
.In
blender/source/blender/blenkernel/intern/mesh_boolean_convert.cc:627
the function is called withnullptr
as the parameter, which is not handled.Breaking commit:

@howardt Do you know why the function gets called with
nullptr
