dmd 2.065beta compiles this with no errors nor warnings:

void foo(ref int i) {
    if (i != 10 || i != 12)
void main() {}

But I think that code should give (I consider this an enhancement request):

test.d(4): Warning: statement is not reachable

Because the (i != 10 || i != 12) condition is always true (also because foo is
not a template function).
