+			     BASH PATCH REPORT
+			     =================
+
+Bash-Release:	5.3
+Patch-ID:	bash53-011
+
+Bug-Reported-by:	Philippe Grégoire <git@pgregoire.xyz>
+Bug-Reference-ID:
+Bug-Reference-URL:
+
+Bug-Description:
+
+If a `mapfile' callback unsets the array variable `mapfile' is using to save
+the lines it reads, `mapfile' can try to reference freed memory, which can
+cause corruption or shell crashes.
+
+Patch (apply with `patch -p0'):
