The latter indeed cannot use DWARF unwinders, but this issue is of no importance to us in this context. The DWARF debug info is certainly supported on x86_64. It's even the default, but -gdwarf-4 makes GCC use more recent version of the DWARF standard, that produces more elaborate debug information.
