Have you tested this with a multi-obj assembler?  I suspect that
something like x86-as --em=i386coff --gdwarf-2 will attempt to
access elf-only data structures.  (That's a slightly ridiculous
set of command line options for x86, but we shouldn't have gas
segfault.)  I think the proper patch needs some new fields in
struct format_ops and defines in obj-multi.h.
