[BZ #4514]
* stdio-common/vfprintf.c (vfprintf): Don't shadow workstart variable, reinitialize workend at the start of each do_positional format spec loop, free workstart before do_positional loops. (printf_unknown): Fix size of work_buffer. * stdio-common/tst-sprintf.c (main): Add 3 new testcases.
