For dec_io_5, the program (intentionally) crashes because "ACTION
conflicts with READONLY" so dec_io_5.txt is never created.

For dec_io_6, the "protected by READONLY" message is (intentionally) a
runtime warning and does not terminate the program, so the following
lines safely delete dec_io_6.txt.

I am not familiar enough with DG to know whether there is a better way
to express the intended behavior of the test programs. XFAIL is the
closest thing I could determine.
