It is because of not matching. Yes, it will leak.

OH! Ok, then! :) Is it particular to that regex, or to not finding results?
(Am I going to have the same problem with the first regex, albeit at a slower
rate because it works better?)
Thanks!

Yes, it has been fixed yesterday.

Hello, all!
I've been working with re_extract() as part of my destination load-balancing efforts. I've got these two lines:
set $!msgid = re_extract($msg, " srcname=[0-9]{1,3}.[0-9]{1,3}.[0-9]{1,3}.([0-9]{1,3}) ", 0, 1, "Unk");
set $!msgid = re_extract($msg, " srcname=\\d{1,3}\\.\\d{1,3}\\.\\d{1,3}\\.(\\d{1,3}) ", 0, 1, "Unk");
If I use the first one, I get steady memory usage, and it actually returns results like it should. If I use the second, it doesn't return any results, and it has ever-increasing until it crashes memory usage.
Even if I got the actual syntax wrong so it doesn't find any matches, it seems like it shouldn't run out of memory and crash. :) This is on 7.4.5.
Thanks!
Robert
