It must be a compiler bug!

Why is it that every fucking moron who decides to start programming insists that any errors in their programs is the compiler's fault? Doesn't it ever enter their thick fucking skulls that if you don't even know the language, just maybe the error is their own?

An important note: left-shift on negative values is undefined.
But as almost every system currently in use has no "arithmetic left shift", it behaves the same as a logical shift.

casting int * to long *
Again, not an issue on most systems.
