Dear Monks

When I compile the following program with perl 5.8.8:

-bash-3.1$ cat -n prueba.pl
     1  use strict;
     2  use encoding 'utf8';
     3
     4  my $x = 'áéíóúñ€';
     5  $x =~ m/áéíóúñ(€)/;

I've got a "segment fault" error:

-bash-3.1$ perl -c prueba.pl
Violación de segmento

Is a Fedora Linux machine:

-bash-3.1$ uname -a
Linux somename.domain.es 2.6.24.2 #3 SMP Fri Feb 15 10:39:28 WET 2008

This is the gcc compiler:

-bash-3.1$ gcc -v

This is the locale:

-bash-3.1$ env | grep -i lan
LANG=es_ES.UTF-8

I tried the same program in a Linux Debian installation with similar results:

lhp@nereida:~/Lperl/src/testing$ perl encoding3.pl
*** glibc detected *** double free or corruption (!prev): 0x08205830 *

Am I doing something wrong? Or is a real bug? May be is already known?

Many thanks
