This is the line which allegdly causes that new bogus warning, but your
report does not include the warning itself. How useful...
Though don't bother to send me the warning. It's going to be completely
bogus anyway as all the other ones.
Thanks,

Sorry for the empty warning here. The actual sparse warning is:
