Eh, there's no (x*)* construct. What's between the parens cannot be an empty string - it's an (xy*)* construct. > > Try instead: /"[^"\\]*(?>\\.[^"\\]*)*"/s > > Nice idea. I anchored it by adding a ^ at the front. Unfortunately it > doesn't work; it still dumps core with the test program I posted. Strange. For me, changing the (?: to (?> makes the difference between a core dump, and not a core dump. I also don't get a core dump on 5.005_04 or earlier. But it dumps core from 5.6.0 onwards, including blead. Replacing (?: with (?> dumps core for me on 5.9.2, but not on 5.9.0 or 5.9.1. It dumps core on 5.8.0, but not on 5.8.[1-7]. 5.6.* and 5.005_* run problem free for me as well. A threaded version of perl5.8.7 dumps core on me though. I guess different versions of perl use slightly more or less memory, which sometimes pushes it over the limit, and sometimes it manages to stay just below the limit. Abigail
