thanks, btw, from the backtrace seems you are playing with reflection ext, but
the
test script you provide doesn't
so, could you please provide us the exact test script you use? thanks

I could, until I restarted computer to check if it's still there... Now it
crashes running from bash, but not from gdb console. I'll get back to you as
soon as it occur again.

will
be very helpful..

Nope, no cache, not even Xdebug nor Zend debug. Pure PHP compiled with
following configuration:
'./configure' '--with-mysql' '--with-pgsql' '--with-zlib' '--enable-calendar'
'--with-curl' '--with-jpeg-dir=/usr' '--with-png-dir=/usr' '--with-gd'
'--enable-bcmath' '--enable-soap' '--with-pdo-mysql' '--with-pdo-pgsql'
'--with-pdo-sqlite' '--with-config-file-path=/usr/local/php54/etc'
'--with-config-file-scan-dir=/usr/local/php54/etc/conf.d'
'--prefix=/usr/local/php54' '--enable-debug' '--with-mysqli'
'--enable-mbstring' '--enable-fpm'
