Hi Adam,

I'm working on PHP7 compatibility for an extension (which I didn't write).
I discovered an issue with a call like this:
call_user_function_ex(EG(function_table), NULL, zval, &retval, 5, params,
0, NULL);
When zval refers to a [object, string] array, its value is different after
this call. I haven't seen this issue when zval is a string. I realize the
context probably matters here, but I'm having trouble narrowing down what
could be doing this. Any suggestions on how to debug this?
The function which handles going from a "callable" zval to an actual
zend_function pointer is zend_is_callable_ex in Zend/zend_API.c, and I
imagine that's where the problem lies.
Perhaps it's a reference-counting/copy-on-write issue?
Hope this helps!
