class declaration in a function with argument causes Compiler bug: Lexical declaration for an unbound name

[mstoykov]

Basically what the topic says.

The following script:

function as(requiredArgument = {}) { // removing the argument seems to work
	class something { }
	let l = new something() // not required
};

gets you

SyntaxError: Compiler bug: Lexical declaration for an unbound name at file:///home/mstoykov/work/k6io/k6/winston.js:3:2
