Bug #83481 for Net-SMTP-SSL: malloc error when running Net::SMTP::SSL on Mac OS X 10.8.2/Perl 5.12.4

I'm running Mac OS X 10.8.2 with Perl 5.12.4 (the version that comes with it). I installed Net::SMTP::SSL via CPAN ('sudo cpan', then 'install Net::SMTP::SSL') Whenever I try to use the perl module, I get an error that looks like: perl(41125) malloc: *** error for object 0x7fff8929d50d: pointer being freed was not allocated *** set a breakpoint in malloc_error_break to debug Abort trap: 6 I've tried to simplify this down as much as possible to narrow down the error. In the following code, it will crash when it tries to run the $smtp->auth line (right after the "About to crash" line). -------------------------------------------------------------------------------- #!/usr/bin/perl use Net::SMTP::SSL; $mailhost = 'foo.bar.com'; $sender = 'baz@foo.bar.com'; $sender_acct = 'baz'; $sender_name = 'Foo Bar'; $sender_password = 'password'; $subject = 'Auto notice'; $userEmail = 'user@foo.bar.com'; $thisMessage = "Hello from Foo Bar\n"; our $smtp = new Net::SMTP::SSL( $mailhost, Port => 465, #Debug => 1, #Hello => 'foo.bar.com', #Timeout => 10 ) or die "Could not set up SMTP $!\n$smtp->message"; print "About to crash\n"; # -- Authorize ourselves with the SMTP server -- $smtp->auth($sender_acct, $sender_password); # -- Enter sender mail address. -- $smtp->mail($sender); # -- Enter recipient mails address. -- @success = $smtp->recipient($userEmail, { SkipBad => 1 }); $smtp->data(); # -- This part creates the SMTP headers you see. -- $smtp->datasend("To: <$userEmail> \n"); $smtp->datasend("From: $sender_name <$sender> \n"); $smtp->datasend("Subject: $subject"); # -- line break to separate headers from message body. -- $smtp->datasend("\n"); $smtp->datasend($thisMessage); $smtp->datasend("\n"); $smtp->dataend(); $smtp->quit(); -------------------------------------------------------------------------------- I'm confident it's not an error in my script, as it works fine when I run it on another platform (Perl 5.8.8 on RHEL5). Net::SMTP::SSL installed without errors. There has been a little discussion of this at http://stackoverflow.com/questions/14974161/perl-netsmtpssl-error-on-mac-os-malloc-error-for-object-0x7fff8929d50, if that's helpful. Thanks, Ian
