Description:
------------
I'm able to reproduce this issue 100% of the time when using pg_connect or pg_query. I've tested with all other extensions turned off and see the same result. The only way I can prevent this segmentation fault is to turn off Zend_MM (which is obviously not a solution).

Core was generated by `/opt/adp/httpd/bin/httpd -X'.
Program terminated with signal 11, Segmentation fault.

Test script:
---------------
any pg_connect call results in a segmentation fault.

Expected result:
----------------
connection to postgres, rather than a connection refused.

Actual result:

Your stackttrace shows that pg_query() is being called. Sure pg_connect() is enough to get a crash? - In the later case I would have expected way more results.

While at it please also mention the version nuumber of pgsql you are using. Thanks.
 [2010-06-02 23:22 UTC] justin_burger at adp dot com 
PG Version = 	8.3.9 

Your right, it looks like it's not happening 100% of the time during the pg_connect. I created a somewhat simple script which causes the fault on every other request. I am able to reproduce this on two different servers. both running 5.2.13 with the 8.3.9 version of postgres.

Code to reproduce: http://pastebin.com/nfNJeyMw

Running this script gives me the following backtrace:

I've done more research and confirmed that I can ONLY reproduce this when using 
postgres as part of session management. executing the exact same SQL outside of a 
session handler does not cause the fault.

This now seems isolated to the session handler use of postgres.
 [2010-07-23 14:06 UTC] miroslav dot zacek at skype dot net 
I think it is the same bug as #52389 I've reported recently (with patch).
 [2010-08-02 17:21 UTC] miroslav dot zacek at skype dot net 
Forget my comment please,it is a different problem.

Do you still have this issue with 5.3>?

Could you paste your session save handler code somehere? (e.g. gist.github.com )
