Floating point exception

I am VisualDSP++ in version 5.0.10 for SHARC 21489 processor.

We are using the RTL functions for the fft calcualtion like twidfftf, gen_hamming, fftf_magnitude.

When we enabled the exception handlers, it is throwing an floating point exceptions SIG_FLTO, SIG_FLTU even when the input data is in the operational domain.

Are there any known issues with the SIG_FLTO(floating point overflow) and SIG_FLTU (floating point underflow) handling?
