I'm not sure that's a valid regular expression... '?' is usually a modifier...
It is...
It allows you to create backreferences but not capture the result directly.

Pretty sure it's supported with the PCRE library. man pcre
SUBPATTERNS Subpatterns are delimited by parentheses (round brackets), which can be nested. Turning part of a pattern into a subpattern does two things: 1. It localizes a set of alternatives. For example, the pattern cat(aract|erpillar|) matches one of the words "cat", "cataract", or "caterpillar". Without the parentheses, it would match "cataract", "erpillar" or an empty string. 2. It sets up the subpattern as a capturing subpattern. This means that, when the whole pattern matches, that portion of the subject string that matched the subpattern is passed back to the caller via the ovector argument of pcre_exec(). Opening parentheses are counted from left to right (starting from 1) to obtain numbers for the capturing subpatterns. For example, if the string "the red king" is matched against the pat- tern the ((red|white) (king|queen)) the captured substrings are "red king", "red", and "king", and are num- bered 1, 2, and 3, respectively. The fact that plain parentheses fulfil two functions is not always helpful. There are often times when a grouping subpattern is required without a capturing requirement. If an opening parenthesis is followed by a question mark and a colon, the subpattern does not do any captur- ing, and is not counted when computing the number of any subsequent capturing subpatterns. For example, if the string "the white queen" is matched against the pattern the ((?:red|white) (king|queen))

It might be a bug in the regular expression library...

Ugh. 2.0.x *should* be built with debugging symbols, and should *not* be stripped of those symbols before being installed.
Yes, and this is from CVS. I'll rebuild with the debug flags... Ok with --enable-developer , it's exactly the same. Grrr
