Description:
------------
I am posting my CrashReporter for apache.  Basically I startup apache 
with the 5.3alpha1 and then go to a page served up by apache and it 
crashes.  It restarts, but most of my CPU gets chewed up as it's 
bouncing back and forth.  Everything compiled fine out of the tarball, 
so I'm not sure what's going on - but in short, right now 5.3 isn't very 
usable on OS X.  Note: I am NOT using the distributed install of Apache 
2 w/ OS X.

  --sysconfdir=/usr/local/php/conf 

No idea what that does, and this is wrong:

  --with-config-file-path=/usr/local/php/conf/php.ini

Note the word "path". Unless php.ini is also a directory..?
Also, you should be using the prefork MPM in apache..

Andrey, I can't reproduce on my linux box, probably a mac issue with the zval cache, can you/we check on a mac?
 [2008-08-01 23:51 UTC] stanlemon at mac dot com 
Would the incorrect config-file-path setting have caused the crashes I'm 
seeing?

Why should I be using the prefork mpm for apache?
 [2008-08-02 16:43 UTC] jani@php.net 
Using incorrect path would not cause a crash, just that you're not then running what you expect. And prefork because any threaded MPMs are not really supported. Best choice: FastCGI.
 [2008-08-02 21:01 UTC] stanlemon at mac dot com 
Wait, I'm not following...  I thought an apache module was always the 
preferred way to compile and run PHP?  Forgive my ignorance here...  I 
guess I'm curious on further explanation?  Also, do you want me to try 
5.3.0alpha1 with recompiling something?
 [2008-08-03 22:07 UTC] jani@php.net 
Try with first changing your Apache to prefork MPM. Then configure PHP with only this:

# ./configure --disable-all --with-apxs=/usr/local/apache2/bin/apxs

Then if this still crashes, we have a real problem.
 [2008-08-03 23:21 UTC] stanlemon at mac dot com 
That seems to have worked.  I tried first with the line you posted 
(though with apxs2 instead of just apxs like posted) and everything ran 
smoothly, then I tried my original configure line (with the two 
corrections you pointed out) and have been successful working with both.  
Is this something that I should post a bug for with Apache, or is it 
related to PHP?

Side note FWIW... it would be handy if someone wrote up an article on 
the benefits of Apache with mpm prefork in an environment running PHP, 
some further detail and such.  

Let me know if there is anything else you want me to test related to 
this.

Thanks again.

My Mac is being repaired, will have it in a month.
 [2008-08-04 21:30 UTC] jani@php.net 
Can you provide a short reproducing script?

Andrey:
Apparently this is some thread safety issue in mysqlnd. 
I don't think you need Mac to reproduce this, just ZTS build.
