It must be zval *params[2] (only one *)
And func_name (not *)

what does it do? I hope it does the following which is needed:
fetch a zval into zval params[0] and zval params[1]

change that to ZVAL_STRING(&func_name, 'someFunc', 0)
(notice & and 0 above)
and don't free func_name, that's unneeded overhead after these changes

here you need &func_name, too
