--- Comment #8 from Jerry DeLisle <jvdelisle at gcc dot gnu.org> ---
With:
if (tmp_symtree)
{
if (tmp_symtree->n.sym && tmp_symtree->n.sym->module
&& strcmp (modname, tmp_symtree->n.sym->module) == 0)
return;
gfc_error ("Symbol %qs at %C already declared", name);
return;
}
We now get:
$ gfc -c pr71649.f90
pr71649.f90:3:7:
USE ISO_FORTRAN_ENV, ONLY : Compiler_Version, Compiler_Options
1
Error: Symbol ‘compiler_options’ at (1) already declared
pr71649.f90:12:29:
Options = Compiler_Options()
1
Error: Unexpected use of subroutine name ‘compiler_options’ at (1)
Which now makes sense.
