The problem occurs immediately when Apache starts up, before any php files 
are acually loaded.   It is totally repeatable - core dumps at the same 
place every time.  A brief bit of detective work with gdb shows the 
following:

> gdb -c core /usr/sbin/apache
...
Program terminated with signal 11, Segmentation fault.
...
(gdb) where
#0  0x20001b59620 in ps_gc_files () from /usr/lib/apache/1.3/libphp4.so
#1  0x20001b59720 in php_gshutdown_ps_mm () from /usr/lib/apache/1.3/libphp4.so

I've had a look at the php source code, but the problem eludes me.
The error appears to be occuring in one of the files in:
  php4-4.0.3pl1/ext/session/
This appears related to the mm (shared memory) module?

Any suggestions welcome?
