Seg fault when calling C code

Time ago I suggested something like that, that is not meaningful 
to accept extern(C) function signatures with ref, [], fixed-sized 
arrays, lazy arguments, associative arrays, pure, and so on, 
because the C side doesn't know about those things or can't 
enforce them (like purity). Walter didn't agree with me, but I 
didn't understand his answer (or I don't remember it now).
