--- Comment #4 from Iain Buclaw <ibuclaw at gdcproject dot org> ---
What fails is gen_decl_die()
---
case CONST_DECL:
─> if (!is_fortran () && !is_ada () && !is_dlang ())
{
/* The individual enumerators of an enum type get output when we output
the Dwarf representation of the relevant enum type itself. */
break;
}
/* Emit its type. */
gen_type_die (TREE_TYPE (decl), context_die);
/* And its containing namespace. */
context_die = declare_in_namespace (decl, context_die);
gen_const_die (decl, context_die);
break;

Here, the condition `!is_dlang ()` returns true because DW_LANG_D does not
exist in DWARFv2.
Would it be correct to fallback on a lang_hooks.name comparison if
dwarf_version < 2?
