Try "volatile int n= ...". What's happening is that the compiler figures out that the result of getColumn... is only used in the following line, so it doesn't bother creating the variable n.
There may also be (likely is) a compiler option that will force it to generate the (to it) useless assignment to n. In the case of the if statement, it's likely being translated as two nested ifs. And then some oddities of how line numbers are mapped probably creates the other factor of two multiplier in steps.
