Tests pass: https://ci.nodejs.org/job/node-test-commit-light/196/
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.

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.
