-----------------------------------------------------------------
Hello,

please excuse my bad english. i hope you will anyway recognize my
bug :-)

here is a little perl-script. i'm sure it is not correct, but i
expected a good error from perl and not a core dump ...

#!/usr/bin/perl

$IDNchars = '\x{E0}-\x{F6}\x{F8}-\x{FF}\x{101}\x{103}';
$string = "m<C3><BC>ller";

print "JA\n" if ($string =~ /$IDNchars/);

($test) = $string =~ /([$IDNchars]*)/;

Here is the result, when i execute the script:

% ./buggyscript
Bus error (core dumped)
%

Regards from Germany,

Diana

(my english is soooo bad - i should do something )
