I found a fairly simple test case for a native vax compile - addftinfo.
It links addftinfo.o, version.o, and libgroff.a with some shared libraries
and resulted in a bad relocation.
I looked at the elf32-vax.c file for libbfd, and started adding some
debug output. I found that it allocates space for the relocation section,
and later outputs the relocations, but did not output all the slots that
had been allocated. Since it was using bfd_alloc(), that left a possible
garbage entry at the end. By changing that to bfd_zalloc(), the unused
relocation entry shows up as R_VAX_NONE. I haven't determined what
particular relocation is allocated but not used yet. I see that a number
of other elf32-* files do the same thing.
