and with 5.4.0 final please :)
 [2012-03-19 10:48 UTC] tim at digicol dot de 
The problem also happens with PHP 5.4.0 final if I use the current APC version, 3.1.9.

If I use the latest APC code from trunk instead:

svn checkout https://svn.php.net/repository/pecl/apc/trunk apc-trunk

... the bug seems to be fixed.

It would be great if a new version of APC containing the bugfix could be released soon.

(By the way: I can reproduce the test case above only if I set "apc.enable_cli=1" in php.ini.)

Thanks,
Tim

I was using PHP 5.3.10 and APC 3.1.9 and was working fine.
After I upgraded to PHP 5.4.3 which is working great alone, APC stopped working, 
so I decided to give a try to "pecl install apc" and I got the invalid pointer 
message explained above.
I'm using Linux kernel 3.2 (Chakra-Linux) + PHP-FPM 5.4.3.
I have no special or custom parameters.
If I disable pthreads when compiling I got a Fatal Error:
Fatal error: Unknown: apc_fcntl_unlock failed: in Unknown on line 0
which makes sense, so I think pthreads questions should be removed because they 
are being used in the APC core.

Regardless the "invalid pointer" error, APC seems to be working and it is being 
listed when phpconfig() is executed.
 [2012-05-15 19:22 UTC] rianob at hotmail dot com 
This bug seems to be fixed in APC 3.1.10 beta.
I installed it using: "pecl install apc-beta" and default compile params.
