Aha! That's progress. It does not show up on my Gentoo Linux box.

On my box, the result is "ret=0, namecount=0".

Yes, it does, because I cannot reproduce it! But it does seem not to be
specifically Windows-related.

I suppose the only way to test that would be to compile a versions of
PCRE with and without the patch, and check. If you are using an
unpatched PCRE 7.7, it does not have that fix on it, however.

I can't do this as I don't ever see the problem (my gcc is 4.1.2).
