35,httpd 2.2.2 crash with xcache enabled,migacr@…,moo,"I am using Apache 2.2.2 and php 5.1.4 on a Linux FC5 server. I have built and installed xcache but httpd crashes at startup where xcache is enabled. Here is the xcache part in php.ini :
{{{
[xcache-common]
;; install as zend extension (recommended), normally ""$extension_dir/xcache.so""
zend_extension = /usr/lib/php/modules/xcache.so
;; For windows users, replace xcache.so with php_xcache.dll
zend_extension_ts = c:/php/extensions/php_xcache.dll
;; or install as extension, make sure your extension_dir setting is correct
; extension = xcache.so
;; or win32:
; extension = php_xcache.dll

; required for >=php5.1 if you turn XCache on
auto_globals_jit = On

[xcache.admin]
xcache.admin.user = ""mOo""
; xcache.admin.pass = md5($your_password)
xcache.admin.pass = """"

[xcache]
; ini only settings, all the values here is default unless explained
; to disable: xcache.size=0
; to enable : xcache.size=any size > 0 and your system mmap allows
; xcache.size =                  0
xcache.size =                 8M
; uncomment and set to cpu count (cat /proc/cpuinfo |grep -c processor)
xcache.count =                 1
; just a hash hints, you can always store count(items) > slots
xcache.slots =                8K

; same as aboves but for variable cache
; xcache.var_size =              0
xcache.var_size =             8M
xcache.var_count =             1
xcache.var_slots =            8K

xcache.test =                Off
; N/A for /dev/zero
xcache.readonly_protection = Off
; for win32, xcache.mmap_path=anonymous map name, not file path
; uncomment and change to ""/tmp/xcache"" for readonly protection

xcache.mmap_path =    ""/dev/zero""


; leave it blank(disabled) or ""/tmp/phpcore/""
; make sure it's writable by php (without checking open_basedir)
xcache.coredump_directory =   ""/tmp/phpcore/""

; per request settings

xcache.optimizer =           Off

[xcache.coverager]
; ini only settings
; make sure it's readable (care open_basedir) coverage viewer script
xcache.coveragedump_directory = ""/tmp/pcov/""

; per request settings, will be auto disabled if xcache.coveragedump_directory i
s not set
xcache.coveragedumper         = Off
}}}

When httpd -X is started, it gives the ""Segmentation fault"" message and crashes.

No problem when xcache is disabled (xcache.size = 0, xcache.var_size = 0).

Any help would be greatly appreciated.
