15feb9a120 Use references for the ExceptionStackFrame argument 
We require/assume that these pointers are correct. Using references is cleaner than blindly dereferencing raw pointers.

Important: The Rust book guarantees that: “At runtime, a raw pointer * and a reference pointing to the same piece of data have an identical representation.”

e8b3a1fff1 Catch divide error instead of page fault 
The divide error pushes no error code. Thus we avoid stack misalignment (see #184).
