 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.)
