Getting this when starting a language server (this is the last one after which it gives up retrying):

I'm able to reproduce this behaviour as follows.

stack new test-yesod yesodweb/postgres
cd test-yesod
stack test --no-run-tests
code .

Navigate to e.g. src/Foundation.hs.

Executing HLS with --debug on src/ results in a segfault:

Hi! could you attach the full log of the vscode session? It seems the error is thrown just after creating a ghc session, stack build/repl works for the files you are opening in the editor?

jneira picture jneira on 4 Sep 2020

That said, the server should not crash without. at least, sending a message to the client

jneira picture jneira on 4 Sep 2020

At a first glance, it reminds me of https://github.com/haskell/haskell-language-server/issues/366, because of the line 

2020-09-03 17:13:28.231839743 [ThreadId 355] - Making new HscEnv[main,main]

Can you tell us something about the project? Is it a stack project, and could explain what you did to trigger this error? (e.g. open src/Lib.hs and waited)

fendor picture fendor on 4 Sep 2020

Agreed, this looks like a cradle issue

Yeah, stack build on the project works fine from the command line:

@fendor

Is it a stack project,

Yeah, created using stack new test rio.

could explain what you did to trigger this error? (e.g. open src/Lib.hs and waited)

I opened src/Run.hs and triggered Haskell: Restart Haskell LSP server via Ctrl+Shift+P.

Let me know if you need more information.

Please post the output of running the following command from the project root directory.

/home/cebaa/.vscode-server/data/User/globalStorage/haskell.haskell/haskell-language-server-0.4.0-linux-8.8.4 --debug src/

I'm seeing the same error in my VSCode log. Running the above command ends with a segfault for me.

I'm able to reproduce this behaviour as follows.

stack new test-yesod yesodweb/postgres
cd test-yesod
stack test --no-run-tests
code .

Navigate to e.g. src/Foundation.hs.

Executing HLS with --debug on src/ results in a segfault:

I'm having the same issue, can be easily reproduced by just creating new Yesod project using stack new my-project yesodweb/postgres and opening VSCode + HLS for this project. @fendor Is there any workaround for this issue at this moment?

In case that it might help as a hint...

I am now experiencing this issue, after I started using Database.PostgreSQL.Simple.SqlQQ#sql QuasiQuoter (from postgresql-simple-0.6.2).

It is back to normal when I avoid using it.
