crash in icBWE for TD stereo at 24.4 kbps

Basic info

• Fixed point:
  • Encoder (fixed):2f76d0ad

Bug description

There is a saturation happening in the function icBWE at frame 1043 of the svtST48c.wav test vector when the TD is forced.

I suggest to revisit it once preprocessing issues for TD stereo (#1124 (closed) , #1125 (closed) , #1136 (closed) and #1142 (closed)) are solved.

Ways to reproduce
