Subject: [PATCH] Test: lock fputcsv enum field Error parity (#5898)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

VmFputcsv already throws Zend’s Error for enum cases in fields (assign and
void). Add repro + compliance PHPT so the php-src-strict contract stays green.
