Save this snippet as throw.js:

function throwAndCatch() {
    try {
        throw new Object();
    }
    catch (e) {
    }
}

console.log("before");
throwAndCatch();
console.log("after");
console.log("the end");

Debug snippet with node builtin debugger:

node debug throw.js

• step over console.log("before");
• step over throwAndCatch();

Observe: the first step works fine but the second doesn't. The program runs to the end.

Commenting out the line with the throw makes stepping work.

The same problem can be observed when debugging in node-inspector or VS Code.

In node versions < 6.0 stepping was working fine.
