Sometimes REPL cannot display the result

[betimer]

• Version: 6.10.1
• Platform: Windows 10 x64
• Subsystem: happens both cmd.exe and powershell

In node REPL mode, when I execute a function, sometimes the result cannot be displayed. Refer as the below screenshot:

I also met for this problem since 6.10.0
Memory leaks may be the main infuential factor of this problem,I guess.
And it just happen in Windows 10 platform,I don`t why?

It sounds like GetVersionEx() is failing but I can't fathom why. Can you try building from source with the patch below applied?

Seems to be a duplicate of #7837. Please try with the latest node.js version.

It is the latest version of 6.x.x already.

It seems #8645 got backported to 6.x, but the libuv upgrade (#9267 and #9647) wasn't. cc @nodejs/lts

I've reverted the offending commit in 1978911, this should be fixed in the next v6.x LTS release

[betimer]

@seishun my node version is 6.10.1 which is latest version of LTS already

I can't tell if this was fixed in 6.10.2 or if it's expected to be fixed in 6.11.2. Can someone confirm the bug on Windows in 6.10.2 or later?

No follow-up and no one complained so I'll go ahead and assume this is fixed. If not, please leave a comment.
