BTW, are you aware that most if not all implementations of realloc() do not
normally do anything if you pass it the same block size?  This sounds too
much like a search for a square wheel to me.

There are no guarantees.  The C standard library describes an interface,
and does not normally determine how that interface should be implemented.
Since memory allocation is by and large very system specific, you're going
way out on a limb using code that will only likely work on two versions of
two specific compilers. Very likely it also depends on which platform
you're compiling for (did you try this with a Windows program, for
example?).

I'm still not sure what you're attempting to achieve that realloc() does
not do already.
