with c7b43a06 and this bitstream : [P800-7-c1a_-stereo_24400_48.zip](/uploads/ff0b609998770456443b210f188fe129/P800-7-c1a_-stereo_24400_48.zip) at frame 863 in the function stereo_icBWE_dec_fx() from file stereo_icBWE_dec.c at Ln1424. ``` IF( LT_16( tmp, 4096 ) ) { temp1_fx = 0; move16(); temp2_fx = 0; move16(); tmp = shl( tmp, 2 ); icbweM2Ref_fx = Sqrt16( sub( 16384, tmp ), &temp1_fx ); icbweM2Ref_fx = BASOP_Util_Divide1616_Scale( icbweM2Ref_fx, sub( 32767, ratio_L_fx ), &temp2_fx ); --->>> icbweM2Ref_fx = shl( icbweM2Ref_fx, add( temp2_fx, sub( temp1_fx, 1 ) ) ); // Q14 } ``` Here again the problem can be solved by using shl_sat(), if we go this way, I think it should be done at line 1395 as well.
