Description:
------------
Ubuntu 10.04 amd64. 100% reproducable on version 5.3.2-1ubuntu4.2 and 5.2.10.dfsg.1-2ubuntu6.4.
On version 5.2.6.dfsg.1-3ubuntu4.5 works fine!

GnuPG extension installed with "pecl install gnupg".

Key import works fine, but signature verification on valid pgp file crashes php.
Any ideas how to further debug and find out whats the reason for crash?

Thank you!

# cat cc.php
<?php
    $gpg = new gnupg();
    $plaintext = '';
    $gpg->verify(file_get_contents('valid.gpg'), false, $plaintext);
?>
