Also looking at c-client's latest, the same internal free happens, so
will cause the same problem.

Ok, I did some investigating and found out it is caused by the fix
#47940.

If no search flags are set, you set flags to SE_FREE, which
mail_search_full then frees the pgm internally, but then you then free
again, causing the segfault. This will be an issue on any OS.

The correct way to do it would probably be to always add the SE_FREE
flag and let it do it itself, and not free in imap_search.

Hm, this version is outdated. Can you try using a decent version? 2007x
(where x is a letter). You can get it here:

I've done a simple build of php using the php-5.2.10.tar.gz from
php.net, and it has the same issue. It still segfaults, and doesn't
contain additional debug information:

./configure --enable-debug --with-imap --with-imap-ssl --with-kerberos
--with-openssl --with-mysql

gdb ./sapi/cli/php
run myscript.php

Program received signal SIGSEGV, Segmentation fault.

The c client I'm using is the one part of CentOS 5.3, 2004g-2.2.1

I added the --enable-debug to the configure earlier, and got a php
build that had a version like:
PHP 5.2.10 (cli) (built: Jun 20 2009 18:09:52) (DEBUG)

I'm not sure why its not adding debug information.

Sorry, the proper ./configure is more like:

configure \
        --cache-file=../config.cache \
        --with-libdir=%{_lib} \
        --with-config-file-path=%{_sysconfdir} \

Please compile in debug mode (--enable-debug) and provide again the
backtrace.

Which c-client version do you use?
