+        * lwlib-Xaw.c (openFont, xaw_destroy_instance): Replace free with
+        xfree to avoid crash when xmalloc overrun checking is enabled.
+        * lwlib-Xm.c (free_destroyed_instance, xm_update_one_value): Ditto.
+        * lwlib-utils.c (XtApplyToWidgets): Ditto.
+        * lwlib.c (safe_free_str, free_widget_value, free_widget_value_tree)
+        (free_widget_info, free_widget_instance, name_to_widget): Ditto.
+        * xlwmenu.c (openXftFont): Ditto.
