Can you run httpd in standalone mode

gdb httpd
(gdb) run -X

and then give me a backtrace of what's segfaulting ?

Httpd cannot be started in gdb. why?  httpd is working outside gdb.  

Sorry, what do you mean run httpd in standalone mode,  i just run apache as normal. This may result in core dump when httpd run with gdb.

Now, i have to use apc.filters = "-phpPgAdmin/.*" to exclude phpPgAdmin's code.

I have the same problem.
But when testing, one time apache's error_log produced these cryptic messages:

I am almost certain this as something to do with postgresql. As vinvinma, my version of postgresql is 8.1 to.  And I don't have any problem with pages which uses no postgresql.

I hope this wil shed some light on the problem.

Oh yeah, one thing.  I can view the page the first time without any problems, it is the second time, cache hit?, that the server crashes.

Please try current CVS and let us know if it is still happening.

where is a CVS server?  I cannot find info on the web.

cvs.php.net

cvs -d :pserver:cvsread@cvs.php.net:/repository login
cvs -d :pserver:cvsread@cvs.php.net:/repository co pecl/apc
cd pecl/apc
phpize
./configure --enable-apc-mmap
make
make install

Thank rasmus!!!  PhPpgAdmin4 is working now in 3.0-dev without filter. I appreicate you resolve this bug.  

However, i hope the other bug : http://pecl.php.net/bugs/bug.php?id=5314, could be resolved as soon as, because we have to turn off APC for PHP5 OO classes which call parent::();

We rewrote a lot package as PHP5 OO style recently, but we cannot cache it.

ok, bug fixed then.  Closing.
