Comment:

 Hmm, this seems to happen because in `checkProddableBlock` the
 `oc->proddables` is NULL. So it has no blocks to check and it errors out.
 Don't know why it errors out and doesn't skip that ObjectCode and continue
 when there are no `proddables`. I'm pretty new at the linker so hopefully
 someone who knows more about this part can explain it.

 Also it won't work on anything prior to 7.10.x since you'll get the
 Unknown PE section error fixed in #9907

 I don't think #9297 is related either, which seems to have more to do with
 the name manglings.
