Look-behind assertion in UTf-8 with JIT compiler unexpected match
Last modified: 2012-04-11 22:43:41 EDT
There is a regression in PCRE 8.21 when matching with JIT in UTF-8 mode. This should not match:
echo ETA | pcregrep -u '(?i)(?<!b|th|z|m|p|^)eta(?!\w)'
Reported to upstream <http://bugs.exim.org/show_bug.cgi?id=1231> and fixed in SVN commit
