[Bug fortran/28397] New: Check format mismatches at compile time

[tkoenig at gcc dot gnu dot org]

It would be nice to check this at compile-time, if possible
(although a lot of compilers don't do this).

$ cat format.f90
program main
  integer :: i
  i = 42
  print '(F10.4)', i
end program main
$ gfortran format.f90
$ ./a.out
At line 4 of file format.f90
Fortran runtime error: Expected REAL for item 2 in formatted transfer, got
INTEGER
(F10.4)
 ^
$ gfortran -v
