No idea. Copying out the test and running it directly, it passes just
fine for me. Maybe gnulib has already replaced printf with its own
malloc-using version by the time it gets to this test??

There was one bug here (failure to set errno when mode string was
invalid) but I don't think that's the case gnulib was testing for. It
seems gnulib wants an error for the "may fail" when the fd is invalid.

gnulib always forces this test to fail if __linux__ is defined.
