Additional log (got it 2 hours ago). log.txt for this build recipe (that is the last one which worked).

This looks like the issue #617 was attempting to fix. @rjodinchr Could you share the solution/workaround you've been using here?

I have just been using #617 for my builds

[twaik]

#617 only hides the problem, it does not solve it.

[rjodinchr]

#617 only hides the problem, it does not solve it.

That's why it has been closed and not merged

[twaik]

@kpet, your verdict?

[twaik]

@kpet what do you think about #628? It makes symbols available (but no-ops) even without CLVK_UNIT_TESTING_ENABLED defined.

[kpet]

@twaik It's not a proper solution but an acceptable temporary workaround. I'll merge the PR and re-open this issue afterwards.
