I see this too on alphaev67 20030923. Test case:

typedef long va_greg;
typedef double va_freg;

typedef struct {
  va_greg * va_next_o;		 
  va_greg * va_next_o_limit;	 
  va_freg * va_next_fp;		 
  va_freg * va_next_fp_limit;	 
  va_greg * va_next_stack;		 
} gnuc_va_list;

int vprintf(const char *, gnuc_va_list);

I suppose the struct is coming from some system header, and is only valid
for that system. Anyway, gcc shouldn't crash.

Zack this is either caused by your in work rewrite of c-decl.c or Geoff's IMI patch but since I know 
you are rewritting c-decl.c again could you look into this bug.
