Confirmed, reduced testcase:
struct DState{
  unsigned char mtfa [4096];
  int mtfbase[256 / 16];
} ;
int makeMaps_d ( struct DState* s, int kk )
{
  int ii, jj;
  for (ii = 256 / 16 - 1; ii >= 0; ii--)  {
    for (jj = 16 -1; jj >= 0; jj--)  {
      s->mtfa[kk] = 16;
      kk--;
    }
    s->mtfbase[ii] = kk + 1;
  }
}
