New Comment:
PHP does not check for infinite recursion for performance reasons.
See also <http://php.net/manual/en/functions.user-defined.php>.
You can install Xdebug in your development environment(s), and set
xdebug.max_nesting_level to an appropriate value.

I think it should not be a segfault error but fatal error like "memory exceed" or too deep
recursion, does it?

This is expected behavior, because the script causes infinite
recursion, see <https://3v4l.org/c1lM1>, what is a
programmer
error.
