Besides ASLR there are various things out of control of the compiler that do
result in varying mapping adresses (like malloc using mmap instead of brk), so
chances are low in any modern system.

I'm not opposed to create a hook for NetBSD, but I have a hard time seeing a
possible sensible implementation. Look at the #ifdef cascade in
config/host-openbsd.c for a disgusting example of code that should not be in a
compiler (IMHO).

How hard is making the externalized format address neutral?
