It is unclear to me if we want to forbid undef to be passed to malloc. It makes 
practical sense but not from a semantic perspective.
However, even if you pass undef you should not get undef back. So the return 
should never be undef for sure. If it doesn, how could you ever deal with it, 
given that a branch on the result would be UB :D
