--- Comment #5 from Iain Sandoe <iains at gcc dot gnu.org> ---
actually fails sooner - Ada and libstdc++ stage1 fail to build (constraint/bus

this is from a cross (which I realise you will not be able to replicate,
without the sysroot etc.) If the reason is non-obvious, I'll try a reduction
later..
