This should be fixed in the latest CVS - please let me know if the problem still occurs.

Derick,
Thanks I did not think to check there this time. I see the following, even with the the $cipher =
md5() and CleanString functions disabled:
[Sun Jul 1 09:11:55 2001] Script: '/home/nerdwww/compose.php'
---------------------------------------
mcrypt.c(1322) : Block 0x08429258 status:
Beginning: OK (allocated on mcrypt.c:1252, 24 bytes)
End: Overflown (magic=0x35653364 instead of 0x2A8FCC84)
At least 4 bytes overflown
---------------------------------------
Here are the calls I make using mcrypt outside of the compose.php script you have already seen:

Thanks again!

Hello,
with debug enabled, do you see any errors in either your httpd errorlog or in /var/log/zenderrors ?

Update:
I have compiled php-4.0.6 with --enable-debug to try and get a backtrace, but when I do, the bug
vanishes and the same code no longer crashed my httpd child process..
Here is some detailed info:
PHP 4.0.6 config line:
./configure --with-mysql --with-gd --enable-track-vars --with-jpeg-dir=/usr/local/lib
--enable-bcmath --with-apache=../apache_1.3.20 --enable-ftp --enable-sockets --with-mcrypt
--enable-debug
and for Apache 1.3.20
EAPI_MM="../mm-1.1.3" \
SSL_BASE="../openssl-0.9.6a" \
./configure \
"--enable-module=ssl" \
"--with-layout=RedHat" \
"--activate-module=src/modules/php4/libphp4.a" \
"--enable-module=rewrite" \
The script that is causing this error is:
http://www.nerdnet.com/compose.phps
As you can see, a use submits a form, which is the source of $cipher, an alphanumeric string, which
is then encrypted and other actions take place after.
I am not using the Zend Optimizer or anything unusual here at all... If I run the httpd thru gdb and
reproduce the crash it gives me an error in shutdown_memory_manager() when it crashes, but not much
else since the bug disappears when I compile in debug into PHP... If any more info is needed let me
know... Thanks PHP team, you guys rule!!!

Can you please post your script as .txt file on the web, so that I can check how the $cipher is
generated?
And is it possibly for you to make a backtrace of this crash
(http://www.php.net/bugs-generating-backtrace.php) as I couldn't reproduce it.
