NullPointerException when calling function 'index' with variable as argument

[mpaluchowski]

Scanning the following code will cause a NullPointerException:

component {
    function foo(required any bar) {
        index(bar);
    }
}

That appears to be due to the use of index(bar). There's no exception when:

• the function name is different than index,
• the function argument is not a variable, ie. is a string,
• the function has no arguments.

will be fixed in next release of cfparser
