Nice idea. I anchored it by adding a ^ at the front. Unfortunately it
doesn't work; it still dumps core with the test program I posted.
I also tried
/^(?>"[^"\\]*)(?>\\.[^"\\]*)*"/s
and
/^(?>"[^"\\]*)(?>(?>\\.[^"\\]*)*)"/s
but both those dump core too.
Are you able to replicate the problem locally with the chomplogs-test2.pl
program I gave? If so, you can try other regexps there. I don't understand
the semantics of ?> enough to be able to assert this is a bug in perl rather
than a bug in my understanding :-)
