XCache 1.3.0 and PHP 5.2.13

Hello,

are XCache 1.3.0 and PHP 5.2.13 full compatible? Or is better downgrade and use XCache 1.2.2 with PHP 5.2.x?

I noted that since I updated XCache at 1.3.0 version it doesn't work more on my server.

Thank you

I am running that setup for the last few months, working fine.
