If node is started with --debug a space appears on the following line

• Version: 6.2.1
• Platform: Windows
• Subsystem: 8.1

FWIW, cannot reproduce on Linux with v4, v5, v6 and master, assuming exit.js looks like this:

console.log('line 1')
console.log('line 2')

A full test case would be appreciated.

well, that is Windows and I wouldn't know what a test case would look like other than what you already can see on the screenshot. And yes, its only those 2 lines you write in exit.js

@nodejs/platform-windows Can someone confirm?

Same here.

C:\Users\Nikolai\Desktop>node --version
v6.3.0

C:\Users\Nikolai\Desktop>node --debug exit.js
Debugger listening on [::]:5858
 line 1
line 2

It seems this happens because WriteConsoleW is called with a string that has a null character at the end here, which the console turns into a space. For some reason the null character is omitted if stderr is piped to a file. Replacing n with n-1 fixes the issue.

Super, Thanks for the fix.
