BASOP decoder asserts in ivas_dirac_dec_binaural_determine_processing_matrices_fx with OMASA rate switching bitstream from BASOP encoder
# Basic info <!--- Add commit SHA used to reproduce --> - Fixed point: - Encoder (fixed): 99e792d197 - Decoder (fixed): 99e792d197 # Bug description There is an assert in BASOP decoder when fed with a BASOP encoder OMASA LTV bitstream containing rate switching. Interop (either direction) does not crash.
