Beschreibung
Assuming one has the following code:
subroutine test_b(b)
real(8) :: b
interface
subroutine test_a
end subroutine test_a
end interface
call test_a
end subroutine test_b
subroutine test_a(a)
real :: a
end subroutine test_a
Intel Fortran frontend fails with ICE that makes difficult to determine a place where the errors are. An example: https://godbolt.org/z/f4hj99f88
The issue comes from using of incompatible interfaces (or declaration + interface) in single file.
