https://www.w3.org/Bugs/Public/show_bug.cgi?id=29253 --- Comment #2 from Tim Mills <tim@cbcl.co.uk> --- I think the main difference between implementations is whether in a regex such as: (.)?a\1 when the "zero case" of the ? quantifier is matched, whether \1 is unbound (and therefore can never match anything) or \1 is bound to the empty string. I think in F&O, it's explicitly the case that \1 is bound to the empty string. e.g. in the online tool, try a(.)? matching a It reports "No match groups were extracted.". -- You are receiving this mail because: You are the QA Contact for the bug.
