+Subject: [PATCH] Fix #77919: Potential UAF in Phar RSHUTDOWN
+
+We have to properly clean up in case phar_flush() is failing.
+
+We also make the expectation of the respective test case less liberal
+to avoid missing such bugs in the future.
+
+(cherry picked from commit cd1101e8c87aa175c2d5e87ddec656e50ef4ab5d)
