This is new, i assume.

This is blocking me fixing the structure aliasing regressions.

I've attached pex-unix.i. Compile with -pendantic to see the crash.

Here is a reduced testcase:
typedef union
  {
    union wait *__uptr;
    int *__iptr;
  } HH __attribute__ ((__transparent_union__));
extern void h (HH) __attribute__ ((__nothrow__));
void g (int *status)
{
  h (status);
}

Thanks,
