Don't play tricks with pointers, period. A little longer: do not access an
object using a pointer to a type different from its natural type. You
defined two longs (or one long long) and were accessing them through
double*. This is invalid. Only exception: you can use char* to access
everything.
If you need to use such things, try -fno-strict-aliasing which will make
your code work. It is generally a bad idea because many optimizers will run
crippled when you disable strict aliasing.
