Confirmed, here is the reduced testcase, any further the ICE goes away:
struct IntPair { int Y, X; };
struct FATyp {
  float *pic; int dx, dy, pitch;
  FATyp (float *Pic, int DY, int DX, int Pitch);
};

int Func1 (FATyp& Weight, double Scale);

int Func2 (FATyp& Weight, unsigned char Arr04, IntPair Mid);
int Func3 (FATyp& Data, unsigned short Pic, IntPair Mid);

int WrkDP (IntPair Pos, float ParA2, int DbgLvl)
{
  float Dat01a [31 * 32]; FATyp TplR (Dat01a, 0, 0, 32);
  float Dat01b [31 * 32]; FATyp TplG (Dat01b, 0, 0, 32);
  float Dat01c [31 * 32]; FATyp TplB (Dat01c, 0, 0, 32);
  float Dat01d [31 * 32]; FATyp TplW (Dat01d, 0, 0, 32);

  float Dat02a [47 * 48]; FATyp SrchR (Dat02a, 0, 0, 48);
  float Dat02b [47 * 48]; FATyp SrchG (Dat02b, 0, 0, 48);

  Func3 (TplR, 1, Pos);
  Func3 (TplG, 1, Pos);
  Func3 (TplB, 1, Pos);
  Func1 (TplW, 1.0);
  Func2 (TplW, 1, Pos);
  Func3 (SrchR, 1, Pos);
  Func3 (SrchG, 1, Pos);
  return 0;
}
