Summary: Impossible to disable Zend Memory Manager in
anything other than CLI SAPI
-Status: Open

Package: Compile Failure
Operating System: Linux Gentoo 2007.0

Works fine here. What SAPI are you using?
/usr/share/nginx/html$ USE_ZEND_ALLOC=0 PHP_FCGI_CHILDREN=0 php-cgi -b 0:9999
$ curl --progress localhost/info.php | grep "Memory Manager"
<tr><td class="e">Zend Memory Manager </td><td class="v">disabled </td></tr>
It's really just coming from the environment:

After compiling with that option Zend MM is still enabled, according to
phpinfo().
Anyway, it must be possible to somehow disable it, because debug build does it.
But it would be not a good solution to use debug build in production.
Please, please check it yourself, *seriously* - no guessing, not requiring me
to check every opportunity.

How about --disable-malloc-mm ??

Well, reproduction script is *not*needed* as it's a PHP configuration setting
issue. It is visible for example in <? phpinfo(); ?> and I gave exact *steps*
to reproduce at the beginning.
Here they are, for convenience:
The goal is to disable the Zend Memory Manager.
Try #1:
1. set USE_ZEND_ALLOC in the environment (/etc/profile)
1a. also tried other ways, like setting it in the Apache config (SetEnv etc)
2. Restart Apache to make sure change takes effect
3. View phpinfo page to see if Zend Memory Manager got disabled
3a. But this way works for the CLI version of PHP (setting env in /etc/profile).
Try #2:
(proven to be futile and ineffective, but anyway)
I tried to recompile PHP with ./configure switches like
--disable-zend-memory-manager or --enable-malloc-mm (some webpages told they
will disable Zend MM), but as other developers said in this report, there are
no such compile options.

So the bug I referred to was http://bugs.php.net/bug.php?id=43397. Curently
it's marked as a duplicate of some other bug, which is now closed because of
lack of feedback. I tried to request reopening my original bug, unfortunately
without success.
About setting env var - please note that I tried this method. No go. phpinfo
shows that Zend Memory Manager is enabled. Note that I didn't set it from
command line, but had in environment (something like export USE_ZEND_ALLOC=0;
/usr/sbin/httpd ...). But it shouldn't make a difference.

How about you tell us what the crash is you get? (what bug id was the one you
reported?) Also note that some crash bugs were fixed recently.
And there are no -disable-zend-memory-manager or --enable-malloc-mm configure
options. To disable the memory manager (for debugging) you start e.g. apache
with same way you do with PHP CLI:
# USE_ZEND_ALLOC=0 /usr/sbin/httpd <your options here>
