Yes.  And most of the discussion (via the gentoo link) is about
powerpc64-linux.

So things were confusing, for me at least.

That almost always runs out of space easier, not less easily.  O3 prioritises
possible speed wins over anything else (*possible* speed wins).

None of the HPPA ABIs are affected by peculiarities of a particular PowerPC
ABI.

The bug report does noty give enough information to see what is really going
on,
so I have no further advice.
