# Basic info <!--- Add commit SHA used to reproduce --> - Float reference: - Encoder (float): f40fa467 - Decoder (float): f40fa467 - Fixed point: - Encoder (fixed): ced61be13 - Decoder (fixed): ced61be13 # Bug description The bitstream from BASOP encoder crashes float decoder with the stack ``` ivas_mdct_core_invQ ivas_mdct_core_dec.c:614 ivas_mdct_core_invQ ivas_mdct_core_dec.c:614 stereo_mdct_core_dec ivas_stereo_mdct_core_dec.c:251 ivas_core_dec ivas_core_dec.c:397 ivas_cpe_dec ivas_cpe_dec.c:420 ivas_jbm_dec_tc ivas_jbm_dec.c:373 IVAS_DEC_GetTcSamples lib_dec.c:1037 IVAS_DEC_GetSamples lib_dec.c:870 decodeG192 decoder.c:2020 main decoder.c:704 ``` Both `ivas-float-update` and current float `main` crash with the BASOP-produced bitstream. The BASOP decoder does not crash. Further observations is that this happens with the encoder built under Linux, but not with one built under ARM-Mac. # Ways to reproduce Using STVs.
