Steps to reproduce:

1) Have following code:
    public int add(int a, int b) {
	return a + b;
    }
    
    public void foo() {
	add(1,2);
    }
2) Invoke Tools|Options|Java Code|Hints|General|Assign Return Value to new Variable
3) Change 'Show As' combo to 'Warning' and confirm OD
=> No warning shown
=> Note that with default 'Show As' setting, the warning is displayed only when carret is inside method call (ie. not
whole current line of code)
