.Net C RunFsc.sh StackOverflowE for --f/w net4.6.1, macOS

[haf]

I decided to give .net core for F# a try (due to the last couple of days problems I've had) for our project. It gives a StackOverflowException during compilation for .Net 4.6.1.

Repro steps

For Mono's clickety-click installer for v5.2.0:

export FrameworkPathOverride=/Library/Frameworks/Mono.framework/Versions/Current/Commands/../lib/mono/4.6.1-api/
dotnet build src/Domain --no-restore --framework net461 --verbosity detailed

using the pattern established here https://github.com/haf/Http.fs/blob/master/Rakefile#L52

To get the logs which contain detailed output, screen-share and/or git repo, please e-mail me at henrik at haf dot se.

Expected behavior

No stack overflows in the compiler bitte.

Actual behavior

Crash and burn.

Known workarounds

Don't use .Net core.

Net 4.6.1 is not even supported on linux, well I suppose it would be if someone put the reference assemblies on the machine in the right place. Does Mono do that? If so, I will see what is necessary to make this work? Kevin

[haf]

Yeah, mono has all the reference assemblies using the export I have in the repro. See dotnet/sdk#335 (comment) and the merged PR here haf/Http.fs#131 and also previous discussion in the F# slack.

Thanks, I will add it the long list of items I need to get to.

Thank you @KevinRansom

I was also following a recommendation here ionide/ionide-vscode-fsharp#511 (comment) by @Krzysztof-Cieslak to see if it was doable.

Hesitatingly posting here with a 'me too' as I am not sure it is the same issue, but on Linux (Debian 9) using .NET Core 2.0.0 I get the same issue, I also have mono 5.2.0.224 installed (as required by ionide). Running dotnet build on my project causes /usr/share/dotnet/sdk/2.0.0/FSharp/Microsoft.FSharp.Targets(224,9): error MSB6006: "RunFsc.sh" exited with code 134. and viewing output of dotnet build /v:diag tells me that it is a stack overflow in fsc.exe (but does not provide an actual stack trace, urgh).

Interestingly, if i run msbuild it works fine. If i then run dotnet build after the msbuild, it also works fine! If I run dotnet clean then dotnet build, error occurs again.

Another point is that my fsproj contains references to another project:

<ItemGroup>
    <ProjectReference Include="../../shared/x/x.fsproj">
      <Name>x</Name>
      <Project>{43366067-2c4d-4ebc-9f69-dde46f401d17}</Project>
      <Private>True</Private>
    </ProjectReference>
  </ItemGroup>

When I run dotnet build ../../shared/x/x.fsproj then dotnet build otherproj.fs, the stack overflow does not occur, however if I just run dotnet build otherproj.fs , it first tries to compile x.fsproj (which appears to work) THEN stackoverflows, so I suspect this matter is to do with multi project builds?

Unsubscribing. If you need me, ping me.

I am going to create this as a separate issue, I have reduced the crash and believe the above to be a false positive on my part.

[KevinRansom]

@xenocons does this: #3658 fix this issue. I think it should.

looping back in @haf , hijacked his issue by accident.

Stale, closing.
