Decoder crash for multi-channel and ISM, BINAURAL_ROOM_REVERB output with specific renderer configuration files

Encoder (float):
Decoder:2b6dc1f3

Bug description

Initial description

Latest main introduced a crash for ISM cases for BINAURAL_ROOM_REVERB output given the rend_config_recreation.cfg as input.

The crash seems to be limited to this specific output&renderer configuration combination.

Update

While starting validation of the BASOP decoder/renderer with room acoustics output it has been found that specific formats combined with specific room acoustics configurations result in fixed-point decoder crash.

The related configuration files:

The input modes affected are multi-channel and ISM. These crashes do not happen with the floating-point variant. The crash does not occur for the rend_config_hospital_patientroom.cfg configuration.
