Comment 11 for bug 11344

I am attempting to locate the code that is the center of the problem,
alot of it is libraries and following the flow is a nightmare at the best
of times.

I have experienced this problem on Redhat Fedora core 2 and Debian
Unstable

I downgraded the following list of packages and the site worked fine

libapache2-mod-php4_4%3a4.3.9-2_i386.deb
libapache-mod-php4_4%3a4.3.9-2_i386.deb
php4_4%3a4.3.9-2_all.deb
php4-cgi_4%3a4.3.9-2_i386.deb
php4-cli_4%3a4.3.9-2_i386.deb
php4-common_4%3a4.3.9-2_i386.deb
php4-curl_4%3a4.3.9-2_i386.deb

php4-pear_4%3a4.3.9-2_all.deb
php4-xslt_4%3a4.3.9-2_i386.deb

after the upgrade things break when these packages are loaded
libapache2-mod-php4_4%3a4.3.10-2_i386.deb

I probably went overboard and installed a heap of pear packages I will not
use but I was trying to get everything up to date as I could so as to
reduce version conflicts.

a apd trace ends with function call is_a, however that function was
called 30 times previous going by the trace

Hopefully I will have some more information in the next few days.
