Small differences in the bit-exactness of floating point calculation are not errors. That's the problem. These happen due to instruction order and register use changes due to the compiler and optimizer. Floating point numbers are not counting numbers, and do not provide bit-exact results. We don't have a test suite for the codec or modem that is tolerant of small deltas of the type that would result from optimization. This kind of problem is going to keep coming up until we do.
