[perl #17611] 5.6.0, 5.6.1, 5.8.0 regexp core on (\@\@|.)*

Able to replicate with 5.8.1.
 
This is a stack size issue:

[robert@x1 /tmp]$ /big/robert/perl-5.8.1/bin/perl -le '$/=undef; $_=<>;
s/(\@\@|.)*//s' regexp_corer
[robert@x1 /tmp]$ ulimit -s 8192 
[robert@x1 /tmp]$ /big/robert/perl-5.8.1/bin/perl -le '$/=undef; $_=<>;
s/(\@\@|.)*//s' regexp_corer
Segmentation fault

(The regex causes the engine to recurse in S_regmatch a _lot_, and kaboom.)

Closing ticket, because I don't think there's anything perl can do about
this.
