This crash happens when decoding multi-channel input coded bitstream but it could happen in any given mdct-stereo core-coder frame. To reproduce use the attached bitstream [bs_48kbps_fb.192](/uploads/48195907bf9cc5df826fdb8da23ba860/bs_48kbps_fb.192) as follows: `./IVAS_dec 5_1 48 bs_48kbps_fb.192 out.wav` Segmentation fault happens at frame 26 line 630 because the cosine pointer `cosPtr`is not assigned. This happens because for the particular frame the length is 240 which is not included as a case in the assignment of tables to the cosine/sine pointers in lines 516-563 of the function.
