--- Comment #6 from Iain Sandoe <iains at gcc dot gnu.org> --- although this was discovered on Darwin, I guess any platform supporting D could be invoked with -gdwarf-2 and that ought not to ICE. I suppose we could adjust configury to decline building D without DWARF >= 3 support. ( I plan to add some support for detecting this for Darwin, system versions with LLDB and dsymutil from LLVM are capable of supporting DWARF-4 - and maybe some earlier cases do support DWARF-3 .. )
