F-line instructions are coprocessor instructions. Perhaps one of the variables
you are using, "bytes" or "num_in" has been defined as a floating point
variable? This is pure speculation, of course, but there's not much I can do
to help you.

Try isolating the piece of code you are using, and then strip it down until the
error does not occurr any more. Then post the resulting pieces of code on
the Lattice BBS, so that the Lattice folks may fix the bug.
