During an update of our FCS fork a pair of our tests started failing with a very strange exception deep in the type checker:

Unexpected exception raised in compiler: The input list was empty. Parameter name: list (ArgumentException)

More exception info from the test output

After the initial investigation I've discovered that the tests don't fail if I build FCS in Release configuration instead of Debug. My first thought here is it could probably been something to do with code generation and optimizations? Though, I'd expect more problems with optimizations applied than without them.

The repro steps for this issue are rather complicated but at least they seem very stable for me:

  • checkout net223 branch or https://github.com/auduchinok/fsharp
  • call ./build.cmd -noVisualStudio
  • build FSharp.Compiler.Service.sln in Rider (or probably using dotnet build)
  • checkout net223-fcsUpdate branch of https://github.com/JetBrains/resharper-fsharp
  • call ./gradlew prepare in rider-fsharp directory
  • restore packages in ReSharper.FSharp.sln (e.g. open the solution in Rider or probably using dotnet restore)
  • take the previously built FCS dll and put it inside the restored NuGet JetBrains.FSharp.Compiler.Service package directory
  • build ReSharper.FSharp solution
  • try running the following tests:

https://github.com/JetBrains/resharper-fsharp/blob/0dc3261b163326f0c947bd19a2cd5599ec2ed9b1/ReSharper.FSharp/test/src/FSharp.Tests/Refactorings/RenameTest.fs#L209-L210

    [<Test>] member x.``Type member - Virtual - Method 01``() = x.DoNamedTest()
    [<Test>] member x.``Type member - Virtual - Method 02``() = x.DoNamedTest()

The tests call ParseAndCheckFileInProject multiple times and at some point it makes the compiler fail with the exceptions from the above.

The SDK used to build FCS is this:

$ dotnet --version
7.0.100-preview.7.22377.5
