Here are three testcases that should be handled when runtime checking is
performed:

Compiling the code in comment #1 gives:

pr31243.f90:12.15:
print *, len(ch)

Error: Result of LEN overflows its kind at (1)
It compiles with -fdefault-intege

I'm not sure how this could be fixed in a "proper way" without breaking the
procedure call ABI. Gfortran follows pretty much every other Fortran compiler
in providing character length as a hidden argument of type default

I am going to look at this for a bit.

This seems to be still in there... Any interest that I work on this? What's
about emitting a warning if either len= or a substring-reference expression is
of a KIND that can have larger values than the machine can ha

Maybe we could just issue a "compiler limit" error
message.

Issuing a warning would be a good thing, "INTEGER*8 value may be greater than
longest possible CHARACTER on your architecture", maybe even a runtime error in
the second case. I hope you're not suggesting that we devise

Same thing happens for local variables, character arguments and character
functions... Example of the first case:
subroutine foo(i)
integer(kind=8), intent(in) :: i
character(len=i) :: x
print *, len(x)
