This is a bug report for perl from [EMAIL PROTECTED],
generated with the help of perlbug 1.35 running under perl v5.8.7.
-----------------------------------------------------------------
[Please enter your report here]
I have recently updated Perl to the 5.8.7 version and have been seeing
some rather weird problem with it. Here's a snippet of code that uses
the Net::IP module :
use strict;
use warnings;
use Net::IP;
my $ips = new Net::IP ("10.0.0.1 - 10.0.0.254");
do {
print "IP: " . $ips->ip() . "\n";
} while ($ips++);
This is the documented method for looping through all the IPs in a
range, and it works as expected with Perl 5.8.6. The '+' operator is
actually overloaded by the Net::IP module and bound to the ip_add_num()
method.
However, this breaks with Perl 5.8.7 for some reason, and you have to
use the ip_add_num() method directly as in the loop below to get the
code to work again :
do {
print "IP: " . $ips->ip() . "\n";
$ips = $ips->ip_add_num(1);
} while ($ips);
According to the Perl 5.8.7 changelog, there should be no incompatible
changes in this release. Any ides why this is happening? Is it just a
plain bug with operators overloading?
Cheers,
Maxime
