libldap-ruby has memory corruption errors

[aprotim]

Libruby ldap creates LDAP::Mod objects by copying pointers, not strings, which means that when the original string is garbage collected, the Mod objects are corrupted.

Attached is a patch that is also being submitted upstream, but as similar bugs have been reported years ago with no response, not holding out a lot of hope on timely response.

aprotim,

Can you provide a test-case, a code snippet, which would demonstrate the bug? I understand it is memory corruption, and it depends on the behavior of the garbage collector and the activity on the system. But still, it would be useful to have something to reproduce the bug.

I have uploaded a fix for this to a PPA based on the patch attached (thanks). Note, this package should only be used to prove a test case - so we can progress for an SRU.

Thanks.
