PS: I claimed ice-on-valid-code as I assume that libstdc++v3 contains valid
code here even though that's not something can really confirm... there doesn't
seem to be an unadorned ICE keyword.

PPS: I still need to figure out how create the preprocessed source during
bootstrap... and I'll try to figure out when this showed up.

Hi,
this does not reproduce on my setup, but the following patch should fix it.
