I had it coming when I started my unittests. But it happened out of
nowhere ^^
Wehen I set USE_ZEND_ALLOC=0 it didn't go away, but instead I got a
debug backtrace (as seen below). But I came up with a solution:
ZendDebugger was the root of all evil. I'll check out if there's a newer
version available...

Problem:
----------
I had this problem when importing an xml file with over 4200 items which
all needed inserting as individual records into a database.
I was using doctrine to insert the records and was creating a new object
for each record, but each time I ran the script it crashed with this
error after inserting exactly 3,579 records each time.
Solution:
-----------
I then decided to try cleaning up the code I had written by using
unset() to destroy the object after it had been finished with. All of
the records were then inserted without any problems.
I would advise anyone receiving this error to check that variables and
objects are being destroyed with unset, because if you think about it
the error is telling you that the zend memory managers heap is
corrupted.

Just for history/logging purposes, I got this same error on PHP 5.2.6 +
MySQL
5.1 + Apache/2.2.4 (Unix) mod_ssl/2.2.4
OpenSSL/0.9.7a DAV/2 + SuPHP on RHEL 4 today.
It was related to mysql_* calls, phpinfo() worked fine, no errors. Any
mysql_*
call crashed.
Code:
---------------
[erom...@roll tmp]$ cat /tmp/test.php
<?php
echo "Hola";
$link = mysql_connect('localhost', 'mysql_user', 'mysql_password');
if (!$link) {
die('Could not connect: ' . mysql_error());
}
echo 'Connected successfully';
mysql_close($link);
Reproducing
---------------
[erom...@roll tmp]$ /usr/local/php5-cgi/bin/php-cgi /tmp/test.php
zend_mm_heap corrupted
Worked fine with USE_ZEND_ALLOC=0
---------------
[erom...@roll tmp]$ export USE_ZEND_ALLOC=0
[erom...@roll tmp]$ /usr/local/php5-cgi/bin/php-cgi /tmp/test.php
PHP Warning: mysql_connect() [<a
href='function.mysql-connect'>function.mysql-
connect</a>]: Can't connect to local MySQL
server through socket '/tmp/mysql.sock' (2) in /tmp/test.php on line 2
X-Powered-By: PHP/5.2.6
Content-type: text/html
HolaCould not connect: Can't connect to local MySQL server through

Updating to 5.3.2 fixed the issue.
Here's the config line I used in BOTH 5.2.6 and 5.3.2, everything
compiled fine
both times. Disregard the unused flags:

Adding
export USE_ZEND_ALLOC=0
to apache2ctl on Ubuntu Hardy worked for me too.
------------------------------------------------------------------------
[2009-11-12 13:38:31] astehlik at intera dot de
I can confirm, that my apache crashed with the error "zend_mm_heap
corrupted" under heavy load. After that I get a lot of Segmentation
faults (11).
OS: CentOS 5.4
PHP: 5.2.11
Apache: 2.2.14
The server is running as a virtual machine in an ESXi 3.5 Server.
I'm now testing the "export USE_ZEND_ALLOC=0" workaround in my
apachectl. I'll provide more feedback as soon as I know if this helps.

I see this error all the time on my complicated application. I am using
php-fcgi + nginx + mongodb so I am fairly sure it is something in core.
I find that even a small change can fix the problem, output buffering
seems to be the culprit for me (ob_end_flush() seems to fix it) which is
maybe why people can only reproduce on production servers?
