http://bugs.exim.org/show_bug.cgi?id=1467 --- Comment #6 from Graycode <[email protected]> 2014-04-22 00:41:37 --- Philip and Zoltan, you are (of cource) correct. My confusion turns out to be that variants of the expressions could match the subject data at the 995 iteration and not at 996. The 996 iteration's non-match causes PCRE to continue with its normal back-tracking and bumping-along in the data seeking a match. The apparent loop is just the massive number of potential match-attempt combinations that has to be dealt with on those expressions. The interpreter exec() halts the loop at an excess of match_limit but as Zoltan stated earlier JIT does not. Thanks for the support & explanations.
