When using xcache.readonly_protection = On, I get the following segfault :

Platform is Linux (Suse 9.2)/PHP 5.1.4 w hardened-php 0.4.9/xcache 1.0RC3
xcache was configured with :
./configure --with-php-config=[...]/php-config --enable-xcache CFLAGS='-O2 -g'
(BTW : can you clean processor_real.c ?)

good report. i'm looking into the segv.
it's out of my control to clean processor_real.c, cuz there's already rules for your "make clean", unless if i may add something like "make xcachesvnclean". but u can do "cat .cvsignore | xargs rm -f".
