This is a bug report for perl from sebastien.rodriguez1@gmail.com,
generated with the help of perlbug 1.36 running under perl 5.10.0.


-----------------------------------------------------------------
Hello,

With perl version 5.10, the module Net::SSH2 fails when trying to use
the Channel.

For example the sample code :
------
use Net::SSH2;
my $ssh2 = Net::SSH2->new();

$ssh2->connect('localhost') or die "$!";

if ($ssh2->auth_password('user','password')) {
my $chan = $ssh2->channel();
$chan->exec('date');
}
----

Fails with "Segmentation Fault" on channel->exec() !

Thank you.
