No response, not yet. syzbot seems to be very slow testing the patches
for this bug report. The earlier ones I submitted also took over a day
to finish.

BTW, even if this patch fixes the problem, I don't think setting
collection[0].parent_idx to -1 is a very good solution. It's brittle
and doesn't address the underlying ambiguity.
