The condition `UNEXPECTED(Z_TYPE_P(key)) == IS_REFERENCE` always returned false, because `UNEXPECTED(expression)` always returns 0 or 1. Move the parens so the comparison is executed properly.

Here's a subtle bug.
The condition
UNEXPECTED(Z_TYPE_P(key)) == IS_REFERENCEalways returned false, becauseUNEXPECTED(expression)always returns 0 or 1. Move the parens so the comparison is executed properly.Note: I found this using a static analyser, and manually verified that the report is in fact a real bug. After fixing this the analyser no longer complains.
