Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves. 

A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external 
resources such as databases, etc. If the script requires a 
database to demonstrate the issue, please make sure it creates 
all necessary tables, stored procedures etc.

Please avoid embedding huge scripts into the report.

i hope i could locate which code occurred these leak. but i failed because it 
run's too much more code. million lines of code running.

any suggestion help me find out the bad code? i tried my hard to find it out 
,but still got nothing.

An easy way to provide more info is to run php under valgrind. It could help to 
locate the issue (for obvious ones). But at the end we may need something to 
reproduce it.

The Valgrind output looks normal. There are a couple of intentional at-exit leaks 
in APC. These are not relevant since they aren't per-request. It is simply memory 
only allocated at process startup and not freed, relying instead on process exit 
to clear it.
 [2013-01-09 23:52 UTC] hufeng1987 at gmail dot com 
it's this APC bug? 

some times it cause PHP segmentation fault
 [2013-01-10 04:42 UTC] laruence@php.net 
could you please give us the backtrace of the segfault you mentioned?
 [2013-01-10 04:46 UTC] hufeng1987 at gmail dot com 
i have configured the core dump environment. still waiting for the core dump. it's 
not always segfault, i hope i could catch it . 

I want to ask, if some code  cause php segfault, it's code's problem or the php's 
problem?

should we fixed it by change the code ? or need to fixed by php upstream?

it depends on what the codes is, and whether it is a known issue.

Disable APC and try again, that will clear this last question.
 [2013-01-10 06:23 UTC] hufeng1987 at gmail dot com 
After disabled APC extension. the memory leaks reporting stopped. what is the 
matter? 

we really need APC , production environment need APC to boost the PHP 
performance．

I was playing with apc using apache, fpm and cli for several hours today. 
Unfortunately no result for this one as well as for #63909. The reproduce cases 
(config, php code) are definitely wanted for those two.

I got about 34 coredump files.

you guys could download more coredump files about these problem.

i had upload it to goolgecode, please download it if you want to analyze them. 

totally contains 34 or more coredump files.

http://php-core-dump.googlecode.com/files/core-dump-20130114-Bug-63950.tgz
 [2013-01-14 09:36 UTC] laruence@php.net 
there is a :
"warning: core file may not match specified executable".

Did you modify exe after it produced the core? Did you perhaps rebuild it with 
different command-line options? It is very important to give GDB the exact same 
binary that produced the core. If you don't, you'll get garbage out.
 [2013-01-14 09:40 UTC] hufeng1987 at gmail dot com 
I am sure i had not modify any exe. i built PHP with debug on. then i waiting for 
coredump. nothing had changes in this peroid.

and there be so much more coredump. at lease 30 coredump files. i upload it to the  
googlecode. hope it will help for testing.

any other need i do ,just tell me how to do.

you need to get the backtrace exactly on that server which generated it.

please make sure there is no such warning:
