/d2/billingd/src/gcc/gcc/libgcc2.c: In function `__negdi2':
/d2/billingd/src/gcc/gcc/libgcc2.c:72: internal compiler error: Segmentation fault

The reduced test case is
typedef int SItype __attribute__ ((mode (SI)));
typedef unsigned int USItype __attribute__ ((mode (SI)));
typedef int DItype __attribute__ ((mode (DI)));

struct DWstruct {SItype high, low;};

typedef union
{
  struct DWstruct s;
  DItype ll;
} DWunion;

DItype
__negdi2 (DItype u)
{
  DWunion w;
  DWunion uu;

  uu.ll = u;

  w.s.low = -uu.s.low;
  w.s.high = -uu.s.high - ((USItype) w.s.low > 0);

  return w.ll;
}


which fails with
