Basic info

• Float reference:
  • Encoder (float):6cf0e3e8
  • Decoder (float):6cf0e3e8

Bug description

with the following command lines and CLANG=1

./IVAS_cod -q -mc 5_1 512000 48 .scripts/testv/stv51MC48c.wav bit
./IVAS_dec -q -fr 20 -render_config scripts/testv/rend_config_combined.cfg -aeid 1:200,0:100,2:500 BINAURAL_ROOM_REVERB 48 bit dec.wav

one can see the following error
