Hi, I tried this on Mac with a new sbt project and dotty 0.25.0-bin-20200604-2fbefb0-NIGHTLY, sbt 1.3.12 using graalvm jdk 8 version 20.0 CE and then AdoptOpenJDK 14.0.1+7. I can't replicate this so please may you provide more information?

[bishabosha]

@letalvoj I see you are compiling 13 sources, perhaps there is some weird interaction. It would be useful if you can see if deleting those files makes a difference, and if so then what is the minimum set of files that cause this issue

[letalvoj]

@bishabosha will do in the upcoming days, sorry for the delay

[bishabosha]

@letalvoj no need to apologise 😀

We made some fixed on that logic recently. It might have fixed it.

Soooo after stripping my project to bare bones I realized that I have a

scalacOptions in (Compile, console) += "-Xprint:typer"

in build.sbt. It works on 0.24.0-RC1.

[bishabosha]

ok thank you, confirmed the lampepfl/dotty.g8 template with version 0.25.0-bin-20200604-2fbefb0-NIGHTLY and scalacOptions in (Compile, console) += "-Xprint:typer" will fail with the given crash in console

[bishabosha]

it still crashes on 0.25.0-RC1

[letalvoj]

scalacOptions += "-verbose"

also causes this issue
