GMP only allocates (reallocates) things when memory (more memory) is
needed, as Niels pointed out.

If you want allocation (reallocation) using the replaceable allocators
to take place also when memory is not needed, then you probably need to
maintain your custom GMP version.

Your statement that "when [GMP] goes to allocate [the custom allocators]
are not used" is simply a misunderstanding of GMP source code.
