    gnuradio-core: trial "fix" for QA failure with debian gcc 4.4.4
    
    Add zeroed 'bumper' space before and after stack allocated input
    buffer in QA code.
    
    Eric Blossom:
    
    "Bottom line, the only thing I can think of that might be going on is
    that we're fetching a NaN off of the end of the input buffer,
    multiplying it by zero (which works for everything except a NaN), then
    propagating that through the rest of the calculation.  (In particular
    alignment cases the code does deliberately fetch either before or
    after the end of the buffer, and it always multiplies those values by
    zero.  If they happen to be NaN's we hosed :-))  In the production
    code we never see the problem since the circular buffer is zero
    initialized."
    
    Note: qa_gri_mmse_fir_interpolator::t1 now fails with the bumper code
    in place.
