--- Comment #2 from Alan Modra <amodra at gmail dot com> ---
I can see one problem when looking at objdump -x under gdb. 
_bfd_elf_get_symbol_version_string is called with symbol being one of the
global_syms (the first one I saw was *ABS*).  Those symbols are not full elf
symbols so the cast to elf_symbol_type is wrong.
