So it's something triggered by a condition in the real bootloader.

It looks like there are several issues are at play here.  There is an
issue with hd0,1, and then there is an issue with error handling.  I
think we should deal with the error handling first, as it will stand in
the way.

It looks like hd0 is ignored.

I think this version has no issues with nested functions.

No, I don't think anymore that gcc is the real culprit here.
