This seems to solve the problem. Thanks for the quick fix @apapirovski!

It would be great if someone else from @nodejs/platform-windows could confirm that this indeed fixes the issue before fast-tracking this. |

You could replace &args[1] with &args.data()[1] to get rid of the conditional.
(It's legal to create a pointer that points one element beyond the array as long as you don't dereference it - which won't happen if argc == 0 because there won't be elements to copy.)

Even better: replace it with args.begin() + 1, since std::copy works with iterators.

Ok, updated now. Thanks for the feedback.

Please use either mine or @bnoordhuis's suggestion to avoid the conditional.

It appears that #18291 broke debug builds on Windows. This should resolve the issue.
@tniessen is currently running a test. If anyone else can try a Windows debug build with this patch applied, that would be appreciated.
