This is completely orthogonal to your MIPS-related changes, isn't it?
I think Mark is on top of the issues about fixing this issue. But it
seems to me it could wait and be considered independent of your
MIPS-enabling work. Since we're not going to have thorough support
for .zdebug_* sections in this release cycle, I'd be inclined to just
leave this area alone for now.
Thanks,
Roland
