+    Do not update StoreEntry expiration after errorAppendEntry() (#1580)
+    
+    errorAppendEntry() is responsible for setting entry expiration times,
+    which it does by calling StoreEntry::storeErrorResponse() that calls
+    StoreEntry::negativeCache().
+    
+    This change was triggered by a vulnerability report by Joshua Rogers at
+    https://megamansec.github.io/Squid-Security-Audit/cache-uaf.html where
+    it was filed as "Use-After-Free in Cache Manager Errors". The reported
+    "use after free" vulnerability was unknowingly addressed by 2022 commit
+    1fa761a that removed excessively long "reentrant" store_client calls
+    responsible for the disappearance of the properly locked StoreEntry in
+    this (and probably other) contexts.
