No, IIRC the issues were with strict aliasing (and, IIRC(2)
something with initialization order, I think we had a discussion
back then).  The compiler messages often left me clueless and
only the compiler people could point me to the underlying issues.

IIRC(3) the itanium arch was the worst and IIRC(4) we tagged
CLN etc as DOES_NOT_BUILD on the arch because nobody was much
interested in fixing there.
