cmsms1.3/centos5.2 Some admin pages are blank due to php abort

[epo]

So far as I can remember I installed cmcms v1.3 on a centos 5.1 virtual host and everything appeared to be fine.

I upgraded to centos 5.2 and now the admin backend is unusable becase of crashes, a typical error report line is

*** glibc detected *** /usr/sbin/httpd: munmap_chunk(): invalid pointer: 0x09337b6d ***

My php5 memory is set to 24M (upping it to 32M made no change), rolling back to centos 5.1 is not possible, any ideas for how to get round this? Doesn't sound like the 1.3.1 upgrade fixed this kind of problem which is why I have asked the question before upgrading.

Edit: cleared the cache - no change.

mysql-5.0.45
php-5.1.6

Even worse, the upgrade.php aborts, reporting that in a separate thread ...
