Nope. This is a grep of a single file, so procfile() must be overflowing
and this only 'fixes' it by relying on signed overflow, which is undefined
behavior, being handled in a particular way by the compiler. So, luck
(which fails when the compiler decides to hate you). There are more places
This seems to fix the issue for me.
OK?

Hello,
I was working on a couple POSIX regular expressions to search for and
validate IPv4 and IPv6 addresses with optional CIDR blocks, and
encountered some strange behaviour from the base system grep.
I wanted to validate my regex against a list of every valid IPv4
address, so I generated
5 matches
