Subject: [PHP-DEV] Problems with APC

I get a segfault with PHP 5.2.0RC2 in
CLI mode (Apache module seems to work)
and APC 3.0.11 (without APC it works
fine). Is this a known problem (maybe
even fixed in CVS) or is it worth
investigating?

Yes, it's a known problem.

But it's an EXTREMELY edge case one. (Only happens with ZTS
enabled, in
CLI mode, with enable_cli not turned on).

I came across this some time ago when mixing Runkit_Sandbox with APC,
just turn on enable_cli. It won't materially impact your
command line
experience.

PHP 5.1.6 & APC 3.0.11-dev crashes on shutdown irrespective of
apc.enable_cli.
