| /* 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(): |
