My project fails to compile when using Scoverage

[markehammons]

Describe the bug

When I try to use scoverage in my project, it triggers nasty compiler crashes on test

Quick Reproduction:

1. go to gitpod.io/#https://github.com/markehammons/slinc/tree/switch-to-scoverage
2. run ./mill j17.test in the console
3. watch the compiler die

Slower Reproduction

1. Clone from https://github.com/markehammons/slinc/tree/switch-to-scoverage
2. Download and/or switch to java 17 (sdkman is helpful here)
3. run ./mill j17.test
4. watch the compiler die

Expected behavior

I expected the compiler to not crash. I believe that the code scoverage generates, and my own (which is heavy on compile-time programming) interfere with each other in this regard

What build tool are you using?

Mill

Version of scoverage

v2.0.7

Thanks for the report @markehammons. However, it looks like it's actually the compiler that is puking here so you'll need to report this in https://github.com/lampepfl/dotty since Dotty is actually generating the coverage here. You'll also want to probably try to minimize if possible.

Actually looking further, it looks like this is actually fixed in nightly for example if you set your scalaVersion to 3.2.2-RC1-bin-20221026-a210b7f-NIGHTLY you'll see that it works. Seems that this pr fixed it scala/scala3#16235. I'll go ahead and close.
