The CI system is a bit "beware of the leopard" with regards to finding 
the failures.

If I go to the link above, I see the message you're copying, but below 
that there is a link "View more details on Azure Pipelines". Clicking 
that takes me to a page that says "build not found" - since the logs 
have been purged since the test was run 2 months ago. Otherwise you'd be 
able to find logs there explaining the failure.

This looks fine.

If I was to guess, from looking at the PR, I would say PatchCheck.py is 
unhappy over the merge commit that has been introduced.
If you rebase your change on top of current master branch and force push 
an update, that will trigger a new CI run, which I'm thinking would pass.

Best Regards,

Leif
