Notice: only on x86_64 (no segfault on x86_64)

Seems related to libtiff version.

Segfault doesn't occurs in RHEL-5 (libtiff 3.8.2) nor RHEL-6 (libtiff 3.9.4) but in RHEL-7 (libtiff 4.0.3) and Fedora (libtiff 4.0.x)

And, as it occurs inside libtiff, not inside libgd, could be a libtiff issue.

Fix #357: 2.2.4: Segfault in test suite.

We make sure to never pass a negative `int` as argument to a `size_t`
parameter.
