Dear Victor,

I need more information. So far, I've never experienced this kind of
problem in other platforms.

As a hint, will you give me struct bit alignment information of SGI 
with -32 and -n32 option. With following struct G__value, I'd like
to know offset of each data member.

struct G__p2p {
  long i;
  int reftype;
};

typedef struct {
  union {
    double d;
    long i;
    struct G__p2p reftype;
  } obj;
  int type;
  int tagnum;
  int typenum;
  long ref;
} G__value;
