First off, I've tried this using PHP4.0.6, the compile works okay with this earlier version (all other software reported below was used with 4.0.6).

The problem occurs under the following conditions:-

Software Versions:
==================
Distro: RH6.2
Kernel: 2.2.19-6.2.12
PHP: 4.1.1
Cyrus IMAP: 2.0.16
UW imap client: imap-2001a
Apache: 1.3.23
MySQL: 3.23.49

Configure:
==========

My configure script is as follows:-

./configure --with-mysql=/usr/local/mysql --with-apxs=/usr/local/apache/bin/
apxs --with-cyrus --with-openssl --with-imap-ssl --with-zlib --with-gdbm=/us
r/include/gdbm --with-imap=/usr/local/uw-imap

configure runs to completion i.e. doesn't complain about not being able to
find something it expects.


Make:
=====

Originally I had some problems with cyrus.c, but a trawl through the bugs on
bugs.php.net furnished an up-to-date version which no longer causes any
probs.

Make eventually fails with the following:-
