http://bugs.exim.org/show_bug.cgi?id=1467 --- Comment #4 from Zoltan Herczeg <[email protected]> 2014-04-21 14:22:50 --- Hi Graycode, I did not fully investigated the issue, but here some analysis: This cause an "infinite" loop: "\".?(.|a){1025}$" This is not however: "\".(.|a){1025}$" (no match) (I suspect we fail the minimum length check) Again, this is not: "\"(.|a){1025}$" (a match) (We reach the end) Again, this is not: "\".?(.|\\x00){1025}$" (a match) (there is no 0x0 character in the input, but there is a lot of 'a') I don't think the loop itself is infinite, just 2^1025 is a really big number. -- Configure bugmail: http://bugs.exim.org/userprefs.cgi?tab=email -- ## List details at https://lists.exim.org/mailman/listinfo/pcre-dev
