Didn't #8017 fix this?

Didn't #8017 fix this?

@TTornblom Can you please review?

@cmonr We need more details for this fix.

[TTornblom]

Yes, #8017 should have fixed this.

[cmonr]

Yes, #8017 should have fixed the issue, but a rebuild of #8023 after the merge did not change anything.

I didn't think that a rebase of #8023 was needed, but my understanding of the mbed2-build job might be incorrect.

@studavekar Does #8023 need a rebase to pull in #8017, which is now in master?

Already rebased. There will be something else going on. This one might be closed

[cmonr]

Closing this since fixes are underway in #8023
