Errors interpreting ldiv values

[iloveeclipse]

Revealed by logging added via #392. The code below produces analysis error Exception processing 'pushByLongMath' with opcode 109, lhs < J, 1 > and rhs < J, 0, cbz > :

package ghIssues;
public class Issue413 {
	public long error_in_ldiv() {
		return 1L / (1L / 2);
	}
}
