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 [Please do not change anything below this line] ----------------------------------------------------------------- --- Flags: category=core severity=high --- Site configuration information for perl v5.8.7: Configured by Debian Project at Thu Jun 9 00:28:22 EST 2005.
