Compiler version

3.1.0

Minimized code

I tried hard to minimize the code triggering the crash, and it turned out if I remove this private opaque type definition (Atry/Dsl.scala@6805444), then the compiler crashes:

git clone https://github.com/Atry/Dsl.scala.git --depth=1 --branch=crash && cd Dsl.scala && sbt compile

It did not crash on the previous commit. The build log can also be found here:

I suspect there is a reference to the symbol of the private opaque type somewhere from the macro generated code, because the error happens when compiling keywords-Fork/src/main/scala/com/thoughtworks/dsl/keywords/Fork.scala, which contains the macro call at https://github.com/Atry/Dsl.scala/blob/crash/keywords-Fork/src/main/scala/com/thoughtworks/dsl/keywords/Fork.scala#L83 , and the macro is defined at https://github.com/Atry/Dsl.scala/blob/crash/bangnotation/src/main/scala/com/thoughtworks/dsl/bangnotation.scala#L732-L737

But it still seems impossible to me. How could macros in another source file be affected because of removing a private opaque type?

I know this is not a good bug report. But this bug is too mysterious to minimize.

I also suspected it's due to some local cache. However, I can reproduce it in a fresh checkout.

It seems that the name or the definition of the opaque type does not matter. Anyway there must be a whatever opaque type otherwise the compiler crashes.

For example:

This does not crash: https://github.com/Atry/Dsl.scala/actions/runs/1568297818
This crashes: https://github.com/Atry/Dsl.scala/actions/runs/1568300361

The commit to trigger the crash:
Atry/Dsl.scala@e7fcf98

I updated the macro, adding some changeOwner and it does not crash any more.
