Build Identifier: 20110301-1815

I'm not sure what kind of error this is so I was not able to search for it.

This problem seems to happen if any statement is in the "if (...)" that would always resolve to false at build time. For example, "if (0 == 1)" also causes the validator to fail.

Doing something like "if ('a'.toLowerCase() == 'b')" will not cause the validator failure.

Using a variable set to false will also not cause the validator failure. An exmaple would be "var a = false; if (a) { ... }".

Reproducible: Always

Steps to Reproduce:
1. Created JavaScript project
2. Create JavaScript source file and insert the following code:

if (false) {
	var a = function(){
		arguments;
	};
}

3. You may need to check Project -> Build automatically.
4. Save the file.
