> dump relocation out of range
This error message basically says that the relation is not a multiple of
the minimum expected alignment. So it seems to be a direct consequence
of the 16bit alignment used on m68k combined with the following from
pdumper.el:
[...]
DUMP_RELOC_ALIGNMENT_BITS = 2,
/* Minimum alignment required by dump file format. */
DUMP_RELOCATION_ALIGNMENT = 1 << DUMP_RELOC_ALIGNMENT_BITS,
[...]
I can't see anything in the code which explains what this alignment
requirement is about. You can try lowering DUMP_RELOC_ALIGNMENT_BITS
to 1 and see if that works (long shot).
Daniel?
