Don't worry, I got what you mean...

Though I don't think coming up with code to fix it is the issue here, in
comment #10 a patch was provided (which admittedly I haven't tested personally)
to turn a void cast into a temporary assignment (which I believe would have
been optimized out later in the pipeline) so I wonder why that hasn't really
gone forward...

Cheers,
Filipe
