+	descr
+		The in-tree gcc 9/gcc 10 crashes with an internal
+		invalid opcode exception when using any kind of
+		optimization on lex.c in usr.bin/xlint/lint .  This
+		was introduced apparently unintendedly in gcc when
+		addressing a different issue.  Rather than disabling
+		optimization for lex.c, instead revert the change to
+		gcc.  The bug report upstream has been updated to
+		reflect the exact breakage.
