This is almost impossible to diagnose. Do you know of any compiler that
detects this?
The only way I see to diagnose this, is to mark all do loop variables as such,
and warn about all assignments to such variables in contained functions. But
that would result in false positives for e.g.
PROGRAM test
IMPLICIT NONE
INTEGER :: i
DO i=1,100
CALL do_nothing()
ENDDO
CALL do_something()
CONTAINS
SUBROUTINE do_something()
IMPLICIT NONE
DO i=1,10
ENDDO
END SUBROUTINE do_something
SUBROUTINE do_nothing()
IMPLICIT NONE
END SUBROUTINE do_nothing
END PROGRAM test
which also seems undesirable... Thoughts?
