[ID 19991130.003] Assignment to List Breaks \G.
Message ID:


Assigning a /gx regexp to a list breaks \G in the following regexp.

    #! /usr/local/bin/perl -w

    $_ = 'a 1 b 2 c 3';

    print "bug\n";
    ($a, $b) = /^(\w)\s(\d)\s/gx;
    print "a=$a b=$b\n";
    ($a, $b) = /\G(\w)\s(\d)/gx;
    print "a=$a b=$b\n";

    print "workaround\n";
    ($a, $b) = ($1, $2);
    print "a=$a b=$b\n";
    ($a, $b) = /\G(\w)\s(\d)/gx;
    print "a=$a b=$b\n";

Output is

    a=a b=1
    a=a b=1
    a=a b=1
    a=b b=2

Here's the configuration of my perl at home, but the one at work,
5.00502, also exihibits this.
