My bad. I was testing the Draft WB.
I was not aware of this PartDesign.Draft tool.
It crashes also for me :

Thanks fellas. Assigned to wmayer to address pre-release.

Doesn't happen in debug mode of OCC because it does a type check and raises an exception because the type is a b-spline. In release mode no type is done causing to access a null pointer.
