--- Comment #6 from Dominique d'Humieres <dominiq at lps dot ens.fr> 2013-02-18 19:21:18 UTC ---
If I do the following changes to the test in comment #5 in order to silence the
warnings " ... may not be C interoperable ... ":

module t
 use, intrinsic :: iso_c_binding

 interface fvec2vec
   module procedure int_fvec2vec
 end interface
contains
 function int_fvec2vec (f_vec, n) result (c_vec)
 integer f_vec(:)
 integer(c_int), target :: c_vec(n)
 end function int_fvec2vec
 subroutine lat_to_c (Fp) bind(c)
 type(c_ptr), value :: Fp
 integer(c_int) :: n1_ic

 integer, allocatable :: ic(:)
 call lat_to_c2 (c_loc(fvec2vec(ic, n1_ic)))
 end subroutine lat_to_c
end module
end

revision 158253 (2010-04-13) gives a (bogus?) error

pr56378_db.f90:17.23:

 call lat_to_c2 (c_loc(fvec2vec(ic, n1_ic)))
                       1
Error: Parameter 'fvec2vec' to 'c_loc' at (1) must be either a TARGET or an
associated pointer

while revision 162456 (2010-07-23) gives the ICE.
