I can't reproduce it in perl, but it's in PL/perl from 9.2 beta built
with perl 5.14.2. Currently I don't have another perl with libperl
installed.

This produces the error:

CREATE OR REPLACE FUNCTION test1() RETURNS SETOF NUMERIC AS $BODY$
use strict;
use warnings;
for (0..9) {
my $rand = rand();
$rand =~ m/(.*)/;
return_next($1);
}
return;
$BODY$ LANGUAGE plperl;

Adding 'elog(NOTICE, "rand:$rand, :$1");' after the capture maked the
error go away. Do does changining the return_next statemtnt to 'my
$retvalue=$1;return_next($retvalue);'
