Thanks a lot for your investigations, Andrew. That explains why all my
attempts to distill a C example for Geoffrey failed. What I don't
understand is whether this very target-specific bug has anything to
do with problems in the Ada front end, is a bug in the back end that
only gets triggered by Ada, or is a result of unclear back end / front 
end
interface. From your description so far, the problem seems to be in
the third category, but if that's the case we probably should also
strengthen the documentation (including comments) a bit.

Also, I think it would be useful at this point if we would be able to
add Ada tests to the GCC test suite, but I have absolutely no clue on
how to do that.
