--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Reduced slightly more:
```
struct _xPoint {
  short x;
} xPoint;
void *reallocarray() __attribute__((__alloc_size__(1)));
struct _xPoint * miZeroLine_pspanInit;
void miZeroLine_list_len(void) {
  miZeroLine_pspanInit = reallocarray(xPoint);
  miZeroLine_pspanInit->x = 0;
}
