--- Comment #13 from Marek Polacek <mpolacek at gcc dot gnu.org> --- Desmond, thanks a lot for reporting these bugs. I believe I fixed all the crashes, although this area is fraught with peril. The mangling part is still largely unresolved. The fix should propagate to Compiler Explorer before long.
