Yes, fixed point it tested in parallel with floating point. Since you
say you're building on windows, is it possible that you haven't setup
the correct defines for fixed point mode? Or is this a cygwin build
configured through autotools?

You're asking CELT for 1.536Mbit/sec output, it's also possible that
you're triggering a fixed-point specific bug. I don't to regular
testing at rates that high.  Does it work at more typical rates such
as 128 bytes per packet?
