This behavior is ANSI standard, but some libc implementations that
claim to be ANSI compliant fail to implement this correctly. IIRC,
some versions of SunOS are faulty for this. The biggest problem with
this IMHO is that relatively few people know how it works, and are
therefore likely to treat this as a bug.
Lua, for instance, does all its memory management through realloc,
but has a special version of it for non ANSI compliant implementations.
