Basic info

• Encoder (float): d18cbee3
• Decoder: 9d43551e

Bug description

Decoding 80 kbps ISM3 OMASA crashes with assertion error in SCE decoding in BWE functions.

Ways to reproduce

Material: LTV

Float encoding

ivas-float-reference/IVAS_cod -ism_masa 3 2 ivas-pc-testfiles/ltv48_OMASA_3ISM_2TC_ISM1.csv ivas-pc-testfiles/ltv48_OMASA_3ISM_2TC_ISM2.csv ivas-pc-testfiles/ltv48_OMASA_3ISM_2TC_ISM3.csv ivas-pc-testfiles/ltv48_OMASA_3ISM_2TC.met -max_band fb 80000 48 ivas-pc-testfiles/ltv48_OMASA_3ISM_2TC.wav test.bs

Float decoding (works, output mode is irrelevant for the crash):

ivas-float-reference/IVAS_dec BINAURAL 48 test.bs float.wav

BASOP decoding (assertion error):

ivas-basop/IVAS_dec BINAURAL 48 test.bs float_basop.wav
