https://www.w3.org/Bugs/Public/show_bug.cgi?id=29253 --- Comment #4 from Tim Mills <tim@cbcl.co.uk> --- As a bit of background, we were formerly passing these tests due to a bug in our regex implementation. e.g. (\w)?(abc)\1b matching against "abcab" It first attempted to match (\w)? to 'a', setting \1 = 'a', but then failed to match 'abc' to 'bca'. Then it backtracked, but forgot to clear the capture group. So it matched (\w)? -> matches empty string, but reported \1 as 'a' 'abc' -> matches 'abc' \1 -> matches the incorrect capture of 'a'. 'b' -> matches 'b' -- You are receiving this mail because: You are the QA Contact for the bug.Received on Wednesday, 4 November 2015 11:14:06 UTC
