I've attached 2 patches. The first avoids an unlikely (impossible?)
integer overflow used for allocating a buffer. It only occurs on systems
with a buggy getgrouplist. The comments say Darwin has the bug, but I
haven't checked which versions. This was found in coreutils coverity.

The second adjusts the module to use reallocarray, instead of
implementing a similar function ourself here.

Will push them in a bit.

LGTM, thanks
