This is a bug report for perl from salva@ubuntu.int.qindel.com,
generated with the help of perlbug 1.36 running under perl 5.10.0.


-----------------------------------------------------------------
[Please enter your report here]

Compiling/parsing complex regular expressions cause perl to SIGSEGV.

For instance:

my $len = 6000;
my $re = join('|', (("a(?:b") x $len), "a") . (")" x $len);
$re = qr/$re/; # ==> Segmentation fault
