+From ec3df00224d4b396e2ac6586ab5d25f673caa4c2 Mon Sep 17 00:00:00 2001

+Date: Wed, 30 Mar 2022 11:14:53 -0700
+Subject: [PATCH] Correct incorrect inputs provided to the CRC functions.
+
+The previous releases of zlib were not sensitive to incorrect CRC
+inputs with bits set above the low 32. This commit restores that
+behavior, so that applications with such bugs will continue to
+operate as before.
