--- Comment #9 from Andreas Krebbel <krebbel at linux dot vnet.ibm.com> ---
The problem is that when processing "getcontext" in elf_link_add_object_symbols
it is matched by the hash entry for "getcontext@@GLIBC_2.2" here:
/* We need to make sure that indirect symbol dynamic flags are
updated. */
hi = h;
while (h->root.type == bfd_link_hash_indirect
|| h->root.type == bfd_link_hash_warning)
h = (struct elf_link_hash_entry *) h->root.u.i.link;
While the name stays "getcontext" the new `h' has the `versioned' flag set.
That's what confuses _bfd_elf_add_default_symbol.
This hack mimics the old behavior of exiting for all symbols not having @ in
their name and fixes the problem for me:
diff --git a/bfd/elflink.c b/bfd/elflink.c
