CB2.0 php5.4/apache 2.4/opcache segfaulting

I am getting white pages and segfaults when i enable opcache with php 5.4 from custombuild 2.0 and apache 2.4

/var/log/httpd/error_log
[Fri May 09 18:52:20.029246 2014] [core:notice] [pid 13416] AH00052: child pid 13420 exit signal Segmentation fault (11)
[Fri May 09 18:52:21.031402 2014] [core:notice] [pid 13416] AH00052: child pid 13419 exit signal Segmentation fault (11)

when i comment the line:
;zend_extension=/usr/local/php54/lib/php/extensions/no-debug-non-zts-20100525/opcache.so
from:
/usr/local/php54/lib/php.conf.d/directadmin.ini

then it is working fine.

anyone a idea?

i did do a rebuild of php after the build opcache
but with the build all d i got the above error

Do you have any other php extensions loaded?
