That code should not compile.

> pure subroutine subx(i,iout) 
> integer, intent(in) :: i 
> integer, intent(out) :: iout 

the first Constraint from 12.6. in the (draft) standard reads:
---
The /specification-part/ of a pure subroutine subprogram shall specify that all
dummy arguments have INTENT(IN) except procedure arguments and arguments with
the POINTER attribute.
---
This is violated here.
