Sorry for the late reply, but no. -1 is meant as a sentinel to say that the
index hasn't been assigned yet.

>From the backtrace, I guess the union's name is probably NULL. But I don't know
why this would happen on ppc64el specifically. If this bug is still present in
current Wine (in particular I wonder if 732f67ed3 made a difference), can you
please attach a log of the output generated when running the offending command
with the additional option "-d 0x3f"?
