Message292183
If 'ignores' is '', you get this:
(?:\b(?:extern|G_INLINE_FUNC|%s)\s*)
which can match an empty string, and it's tried repeatedly.
That's inadvisable.
There's also:
(?:\s+|\*)+
which can match whitespace in multiple ways.
That's inadvisable too.
If the pattern really doesn't match the string (and it doesn't!), then it won't find out until it has tried _all_ of the possibilities.
Some implementations, such as Perl's, have extra checks to try to reduce the problem. |
