It does look like I can replace the realloc calls:
1753 #define MPZ_REALLOC(z,n) (UNLIKELY ((n) > ALLOC(z)) \
1754 ? (mp_ptr) _mpz_realloc(z,n) \
1755 : PTR(z))
which bypasses any replacement of __gmp_reallocate_func.
So, for example, in mpz/n_pow_ui, when it calls MPZ_REALLOC, I'm stuck
with the abort()
In fact, it appears that very few places in the code leverage
