There is no documentation for installing and using the XCache admin pages. A page explaining what each variable meant would be helpful.

When using the default ini settings (xcache.mmap_path = "/dev/zero"), xcache removes /dev/zero :

strace gives this : [pid 28606] open("/dev/zero", O_RDWR) = 18 [pid 28606] ftruncate(18, 33554432) = -1 EINVAL (Invalid argument) [pid 28606] mmap2(NULL, 33554432, PROT_READ|PROT_WRITE, MAP_SHARED, 18, 0) = 0xb47b9000 [pid 28606] munmap(0, 33554432) = 0 [pid 28606] close(18) = 0 [pid 28606] unlink("/dev/zero") = 0 [pid 28606] getuid32() = 0 [pid 28606] open("/tmp/.xcache.0.0.1804289383.lock", O_RDWR|O_CREAT, 0666) = 18 [pid 28606] unlink("/tmp/.xcache.0.0.1804289383.lock") = 0 [pid 28606] open("/dev/zero", O_RDWR) = -1 ENOENT (No such file or directory)

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 ?)
