+Subject: [PATCH] gdatetime: Fix comparison against cached LC_TIME value
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The string pointer returned by `setlocale (LC_TIME, NULL)` may change if
+other code calls `setlocale()` again. But because internally glibc
+implements it using `strdup()`, the pointer value itself may actually
+stay the same even if the string contents change.
+
+This started happening more commonly in glibc 2.43, due to an internal
+`malloc()` change which happened to trigger this latent bug.
+
+In the situations where this happened, it resulted in an outdated cached
+era value being used.
+
+Fix it by taking a copy of the `LC_TIME` string. Unfortunately this
+means a reachable (‘leaked’) static string allocation at the end of the
+process’ life, but tooling should ignore that if we mark it with
+`g_ignore_leak()`.
+
+Debugged by Sam James, Wilco and Douglas R. Reno. See also
+https://sourceware.org/bugzilla/show_bug.cgi?id=33899#c6.
