Eh?  I don't recall filing or modifying this PR.  How did you
determine I was responsible?

Anyway, the patch (or suggested change) in there looks technically
correct to me.  But I would instead do something like the patch below.

(I'm not sure how to test it since I don't have code any handy that
causes ld to crash.)
