Bug description

IVAS BASOP IVAS_rend crashes when trying to create MASA2 output from OMASA config that has ISM1 + MASA2 inputs.

Ways to reproduce

This works

ivas_rend_float -if META -i ism1_plus_masa_scene.txt -of MASA2 -o float_masa2.wav

This crashes with "Assertion failed: 0, file C:\Code\ivas-basop\lib_com\basop32.c, line 2590"

ivas_rend_basop -if META -i ism1_plus_masa_scene.txt -of MASA2 -o basop_masa2.wav

The short test vector files that can be used are:

• stvOMASA_1ISM_2MASA2TC48c.wav
• stvISM1.csv
• stv1MASA2TC48c.met

In addition following scene file can be used.

ism1_plus_masa_scene.txt

Also -of MASA1 will crash similarly.
