Windows XP SP2, Apache 2.0.58, PHP 5.2.0, php_apc.dll (RC3-dev).

Apache starts normally, apc.php runs as expected. Visit a page: apc.php shows cached files as expected. Visit another page: crashes Apache, which instantly restarts. Seems like it crashes every other page. When APC is not loaded, Apache never crashes.

No error in the PHP error log (E_ALL|E_STRICT), nor in the Apache one (except the usual stop/start messages).

Note: before upgrading to 5.2.0 I was running 5.1.6 and APC never crashed Apache while running, yet it crashed Apache when I was manually shutting it down/restarting (twice during the stop process).

APC configuration:
apc.enabled        = 1
apc.shm_segments   = 1
apc.optimization   = 0
apc.shm_size       = 128
apc.ttl            = 7200
apc.user_ttl       = 7200
apc.num_files_hint = 768
apc.enable_cli     = 0

Windows Application Error report:
Description :
Application d?faillante Apache.exe, version, module d?faillant php5ts.dll, version, adresse de d?faillance 0x00097d80.

I'm having this exact same issue, except I'm using IIS & Windows 2003. With APC enabled, the first page requested will load, upon refreshing the page, IIS crashes. It seems the 5.2.x version of APC is flawed.

I too am having the same issue.

Win 2K server, IIS 5.0, PHP 5.2.1

Enable php_apc.dll within the php.ini and the second page loaded brings up the dreaded "access violation" error :(

Remove the php_apc.dll from the ini and restart the web service and the site works perfectly again.

Is this bug present in 3.0.13 release as well ?

Does any body found a solution for this? Man..I've been hitting on this for ages now but in vain. Even the pecl4win site is down for upgradation.

Have you tried one of the temporary builds from here?:

Thank you for this bug report. To properly diagnose the problem, we
need a backtrace to see what is happening behind the scenes. To
find out how to generate a backtrace, please read for *NIX and for Win32

Once you have generated a backtrace, please submit it to this bug
report and change the status back to "Open". Thank you for helping
us make PHP better.

Any chance of trying to provide a backtrace to see where it crashes? Aswell as trying with the APC 3.1 branch and or the latest 5.2/5.3 stable PHP branches?
