In cartable.hpp:

  int get_index(const void* p) const {
    uintptr_t pi = (uintptr_t)p;
    assert((pi & ((1 << LogOfCarSpaceSize)-1)) == 0,
           "boundary pointer must be valid for CarTable");
    assert(sizeof(pi) == sizeof(jint) || high(pi) == -1,
           "High word must be all ones");
    return get_index_work(p);
  }

for 64-bit sizeof(pi) is not sizeof(jint), but high(pi) is not -1 on all platforms. So we hit this assert (on HPUX and Linux).
