I think some of this code is showing its pre-C++ origins, but I wonder
if you'd be better using symtab_to_fullname() instead of accessing
symtab::fullname() directly?

It's not entirely clear, but I think, this will always return
non-nullptr, and will have set symtab::fullname() if needed.

Thanks,
Andrew
