Fortran: Fix ICE on invalid code
This patch tests whether a symbol imported into an interface
is already available in local scope.
PR fortran/123375
gcc/fortran/ChangeLog:
* decl.cc (gfc_match_import): Check that imported entity
within
a interface is not from local scope.
gcc/testsuite/ChangeLog:
* gfortran.dg/import.f90: Run code testing for a warning that
is now an error.
* gfortran.dg/pr123375.f90: New test.
Hi Jerry,
technically speaking, the following error may confuse users as it
is a little misleading:
module bar3
implicit none
interface
subroutine bah
use foo
import aa ! { dg-error "already in the local scope" }
end subroutine bah
end interface
end module bar3
aa is not available in the host, as detected by other compilers
(e.g. NAG), but I think we can live with it.
Otherwise OK from my side.
Thanks for the patch!
Harald
