I have this problem too.
Configuration: PHP 5.2.8 (Win32), Apache 2.2.11, MySQL 5.1.31, OS
WinXP.
I have this bug, when i try run phpmyadmin (all versions). Apache
restarted and i found in apache's logs the message "zend_mm_heap
corrupted".
Sorry, my english is weak ;-)

I'm surprised this isn't being talked about more. I see it
occasionally, and I am using Zend Framework. Why don't other people
using ZF see it?

Soletan, thanks for advice but it seems that Suhosin is not 100%
solution. We are running Ubuntu Hardy (8.04 LTS) server, 32bit. Using
standard PHP 5.2.4 Apache2 module package which already includes Suhosin
patch. We still experience this bug...

Ran into the same problem and read most of the posts in this report.
Well, I don't expect PHP developers to ever find this bug. Don't you get
annoyed by template-driven posts asking for information they can't use?
HERE COMES MY ADVICE: Reading hints on expecting a race condition lead
me to installing suhosin, which is an extension to PHP increasing its
integrity and security. Guess what, it helped me out of this trouble.
This is no ad, so I won't provide a link here. Just google the name ...
Maybe PHP developers shouldn't use templates requesting tons of
backtracks providing obviously useless information, but invest some time
in revising observers for the internal memory management of PHP as this
is obviously causing the trouble.

The same problem appears from a allegedly successful compilation op PHP
5.2.9 on RHEL5 64 bit using -m32 CFLAG so that the binaries are 32 bit.
The compilation appears to complete successfully:
Apache 2.0.59 compiled w/o any problems with the following configure
and it works fine.
./configure --prefix=/apps/apache2 --with-expat=builtin
PHP is configured with the following options:
./configure --with-apxs2=/apps/apache2/bin/apxs
--build=i386-redhat-linux --with-pic --with-gd --with-zlib
--with-config-file-path=/apps/apache2/conf --with-libdir=/lib/
--enable-debug
And after the successful run, make test was run with the following
errors:

I think this is because the configure script assesses the intmax_t as 4
as opposed to 8 and all of the integers are overflowing with 4 bytes.
Just a guess but comparing to an other environment where I managed to
compile it successfully, these appear to be the main differences in
config.log.

Apache/2.0.63 (Win32) PHP/5.2.8
FWIW, this happens when running as a service. Running in the console
it's fine.
I found it in response to bug #46842, after rolling back from
Apache/2.2. I cannot say for sure if they are related.
