COFF debugging info bug

[Laurynas Biveinis]

Current CVS gcc will segfault for following f.i, when
invoked as

./cc1 -gcoff f.i

typedef int sword __attribute__ ((mode (SI)));
typedef unsigned int uword __attribute__ ((mode (SI)));
typedef unsigned char ubyte;
struct dwarf_cie {
  uword length;
  sword CIE_id;
  ubyte version;
  char augmentation[0];
} __attribute__ ((packed, aligned (__alignof__ (void *))));

Can anyone look into this?

TIA,
Laurynas
