I'm not convinced. My assumption is this is triggered because the local pow_10
function was returning int whereas generic int_pow is returning an int64.
Whilst I would imagine it is fairly easy to fix, I'll not have a chance to do
so until the weekend. Perhaps we should just revert this patch and revisit
in the next cycle?
0-day people, any idea why the iio.git/testing branch isn't getting built any
more? I got lazy and started relying on your infrastructure and not bothering
with 32 bit local builds. Somewhere along the way you stopped building it
and I'm afraid I didn't really notice.
Thanks for you all your hard work on 0day btw as it used to catch a lot
of stuff my local few builds didn't!
