Can you retest with the latest CVS? This seems to have been fixed (i.e. I can't
reproduce it).
If not, re-open this bug report.

We are using PHP as an Apache module, and are using mcrypt functions in our scripts,
and we get segmentation faults. We have submitted queries at a few
forums, and gotten no answer that will help us. This not only happens at the server
from which we're delivering logs and other data, but at other servers,
with diferent kernels, apache versions, even diferent distribution versions. We have
tried configuring php in many diferent ways, but we keep getting the segmentation
faults.
We run: gdb /apache/bin/httpd and at gdb prompt: run -X
and then when we try to browse the php script (included after this gdb log):
--- begin gdb log ---
This GDB was configured as "i386-redhat-linux"...
(gdb) run -X
Starting program: /apache/bin/httpd -X
Program received signal SIGSEGV, Segmentation fault.

Here are some other details that we hope might help you.
We're using Red Hat Linux release 6.2 (Zoot), with the default kernel
(2.2.14-5) on an intel processor:
model name : Pentium III (Coppermine)
stepping : 3
cpu MHz : 598.075823
The software we think is involved in causing this problem is:
Apache:
melpomenia:/apache/bin# /apache/bin/httpd -v
Server version: Apache/1.3.17 (Unix)
Server built: Feb 6 2001 10:25:18
PHP:
php-4.0.4pl1
./configure --enable-bcmath
--with-db2 --with-apxs=/apache/bin/apxs
--enable-shmop --with-zlib --enable-track-vars --with-ftp --with-gettext
--with-mysql --with-gd --with-mcrypt --enable-sysvsem --enable-sysvshm
--with-mhash --without-xml --disable-xml --enable-debug
LibMcrypt (which is what we suspect is causing the segmentation faults, from the
straces we have run, as well as from the fact that we only get segmentation faults
when using mcrypt functions in the scripts).
libmcrypt-2.4.4

Thank you for your wonderful scripting language, we hope we can help you make
it even better :).
