Hi guys,

Just a quick question, as I am quite puzzled about the verdict difference.

Those two codes are identical, but it passes in G++17 and fails in G++14.

G++14 Verdict

G++17 Verdict

Locally, those two seem to both produce -2 as an answer for the first test case for both G++14 and G++17.

I am guessing I made a trivial mistake somewhere.

Could you guys enlighten me with why it passes on one but not the other? I am guessing it could be due to using unsupported/undefined behavior in G++14.

Thanks a lot!
