Reduced testcase:

VBR_encode_frame (int mode_gr, int channels_out, int max_bits[2][2])
{
  int max_nbits_ch[2][2];
  int gr, ch;
  for (gr = 0; gr < mode_gr; ++gr)
    {
      float f[2], s = 0;
      for (ch = 0; ch < channels_out; ++ch)
        if (max_nbits_ch[gr][ch] > 0)
          s += f[ch];
      for (ch = 0; ch < channels_out; ++ch)
        if (s > 0)
          max_nbits_ch[gr][ch] = 7680 * f[ch] / s;
    }
}
