Comment #1 on issue 1259 by [email protected]: RegExp matching is too
slow in case of iterative matching of alternatives
http://code.google.com/p/v8/issues/detail?id=1259
The timeout even occured without alternatives. It is sufficient if the
pattern contains
an iterative term enclosed by an iterative group.
E.g.:
'xxxxxxxxxxxxxxxxxxxxxxxxxxx'.match(/(x*)*a/);
I think the reason of the timeout is the same as in the case of iterative
matching of alternatives.
The problem is same in the mozilla test suite: ecma_3/RegExp/regress-330684
(see test/mozilla/mozilla.status).
The mozilla.status refers to "V8 bug 676063" but it seems is a ghost bug.
