I can reproduce the bug with gdb if the file descriptor 0 is closed before calling:
    std = create_stdio(iomod, fd, 0, "<stdin>", encoding, errors);
and after the following lines were called:
    fd = fileno(stdin);
    if (!is_valid_fd(fd)) {

In initstdio () at Python/pylifecycle.c:1156.

create_stdio() fails in FileIO constructor, on the line:
   if (_Py_fstat(self->fd, &fdfstat) < 0)
of _io_FileIO___init___impl() at Modules/_io/fileio.c:480

It's a corner case of the issue #7111, I would call it a race condition.
