OK, no testcase needed.  Yes, the bug is that h8300_bfd_link_add_symbols
uses h8300_coff_hash_table without first checking the hash table
creator.  I fixed a bunch of similar bugs in ELF targets with my
2002-04-16 bfd change.  Until one of the COFF maintainers looks at this
problem, I'm afraid you'll need to link to COFF output, then use
objcopy to convert to srec.
