+/* From: Denis Vlasenko <vda.linux@googlemail.com>
+ * With certain combination of .config options fclose() does not
+ * remove FILE* pointer from _stdio_openlist. As a result, subsequent
+ * fopen() may allocate new FILE structure exactly in place of one
+ * freed by previous fclose(), which then makes _stdio_openlist
+ * circularlt looped. The following program will enter infinite loop
+ * trying to walk _stdio_openlist in exit():
