It is kind of the same issue only this time, it expects it to be a variable length args function. @cmb69 did I got it right ?

@devnexen, the problem is again that operator overloading is used, but not a function. The implementation of zend_parse_arg_long_slow() calls zend_null_arg_deprecated() for NULL arguments, and that function always expects to be called from a PHP function. PR #16015 would solve this by rejecting NULL values for operator overloading.
