This is a bug report for perl from barries@slaysys.com,
generated with the help of perlbug 1.34 running under perl v5.8.0.


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

Get the file http://slaysys.com:81/regexp_corer and do:

    perl -le '$/=undef; $_=<>; s/(\@\@|.)*//s' regexp_corer

This produces a segfault in 5.6.0 and 5.8.0.  Using a bigger
chunk of that file can trigger it in 5.6.1.  Can't get 5.004
to hork.

[Please do not change anything below this line]
