Formatted read or write with no variable list needs a format (fmt)
string longer than one character.
This is checked already -- partly -- but very good, indeed.
Please take a look at the message text.
$ cat z_write_fmt_too_short_1.f90
program p
character(1), parameter :: fmt1 = '('
character(1) :: fmt2 = '('
write (*, fmt1)
write (*, fmt2)
write (*, '(')
end
$ gfortran -g -O0 -Wall -fcheck=all z_write_fmt_too_short_1.f90
