Subject: Problems with APC, was Re: PHP 5.2.0RC2 Released!
From: cschneid@cschneid.com (Christian Schneider)

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?

Some info:
