Apparently it's been open for over three years. Since this is a known bug, I won't file a new report, but I'm wondering if anyone would be kind enough to take another look at fixing it. From the bug tracking notes, it looks like the fix is nontrivial, at least for users unfamiliar with gcc internals (myself). I'd be happy to do testing on my end if someone figures out a solution. Thanks! Cc'ing the listed maintainer of the m6812 target, Stephane Carrez. Ian
