BASOP assert in OSBA ISM4SBA1 fx encoder with +10dB gain

Basic info

• Encoder (fx): 2d6d9ca8

Bug description

OSBA verification input triggers assert in encoder:

IVAS_cod_fx: lib_com/basop32.c:1786: L_add: Assertion `0' failed.

The file is a specially tailored item with almost identical channels with produced music content. Applying the 10dB gain already introduces severe clipping. Might be that #823 (closed) is related.
