gmp: overflow in mpz type
Not sure whether this has now been fixed upstream, but a discussion
suggests that LP64 like here is fine, so that there shouldn't be
such a limit.

I just tested with GMP 6.3.0 and encountered a different symptom:
./a.out
i = 30
i = 31
i = 32
i = 33
i = 34
i = 35
i = 36
i = 37

I think that any changes to address this bug ultimately do belong in an
upstream
discussion rather than a Debian bug. Therefore, I'm closing this.
