! This program tests that the CFI_establish function properly detects
! invalid arguments.  All the interesting things happen in the 
! corresponding C code.
!
! The situation here seems to be that while TS29113 defines error codes
! for CFI_establish, it doesn't actually require the implementation to detect
! those errors by saying the arguments "shall be" such-and-such, e.g. it is
! undefined behavior if they are not.  In gfortran you can enable some
! run-time checking by building with -fcheck=all.
