java.lang.AssertionError: NoDenotation.owner when compiling with coverage

[reid-spencer]

My GitHub workflow compiles my project with sbt-scoveralls plugin active to run the tests with coverage enabled. In that case, dotty yields an AssertionError. Note that regular compilations do not produce this symptom. This was a surprising result. The impact of this issue is that my project won't be able to produce coverage metrics until this is fixed (i.e. not a huge deal).

Compiler version

3.3.0
(does not occur in 3.2.2)

Minimized code

Minimizing this could take a while.

In the meantime, reproduction of it is quite straightforward.:

• Clone https://github.com/reactific/riddl.git
• Edit project/Helpers.scala in the withScala3 function, choose a scalac version you want to test (3.3.0 based)
• Run sbt in the cloned directory and:

> project language
> clean
> coverage
> Test/compile

You can see the issue from where it was detected in this GitHub Workflow Output.

This is all the help I can provide for now. If a smaller test case is needed, please let me know.

[som-snytt]

This surfaced on discord, so it must be a thing.

#17605

[jchyb]

This appears to be a duplicate, but I'm going to leave it so we can test when the fix is made for the other issue, without making a second (potentially redundant) minimization

[pribor]

It is worth mentioning that it works in 3.3.1

[reid-spencer]

Confirmed. I rebuilt with 3.3.1-RC1, and it compiled without complaint.
