I have the Sybase 11.0.3 client libraries installed. When 
compiling with IMAP support, the following script produces 
a segfault:

<?php
    $c = sybase_connect("GALAXIA", "sdjfk", "sdjf");
?>

(where GALAXIA is a valid interface and the user name and 
password are invalid).

The segfault does not occur if LANG is set to an invalid 
value.

The problem goes away when compiling --without-imap.

The 11.9.2 Sybase libraries also segfault if LANG is set 
to a *valid* value. The segfault goes away --without-imap.

I suspect the culprit in the fact that libct.so (from 
Sybase) and c-client.a (from IMAP) both contain a symbol 
'net_close'. This symbol has prevented me from static 
linking in the past.

Bug 3161 et al. may be related.

Update your Sybase libs since this has been fixed in them.
(I don't know since which version, in my 11.9.2 version the
offending function is renamed to syb_net_close() )
