I'm on the road all week (leaving in about 20 minutes). I can fire up a
bootstrap after I return.
However, I doubt that's going to be all that useful. The bootstrap is clearly
failing on your end and from the way it sounds, it's unlikely I'll trip
the failure here. This really needs to be debugged on your end.
So, what happens if you compile one of the failing .i files with the stage1
and stage2 compilers? Do you get the same .s file or ones that differ?
