[Bug regex/1291] New: size-overflow bugs in the regex code

- Reply-to: sourceware-bugzilla at sources dot redhat dot com
The regex code currently misbehaves badly if there's an arithmetic
overflow when calculating sizes, e.g., when doubling buffer sizes.
I'll attach a patch for all the instances of this that I found. These
patches are conservative, in the sense that when I couldn't determine
whether an overflow was possible, I inserted a run-time check.
