I'm reasonably confident that both of those problems are fixed now. The former would certainly elicit a warning from gas, and I don't see any of those in the log. But there could well be other, similar bugs still lurking. >Is it possible to arrange for the buildd either to use a different >optimisation level, or to temporarily use a new (or older) compiler? I'd rather not tinker with the buildd's environment, but I'm happy to try compiling with different sets of options. p.
