HLS loops - out of memory? (Assertion `freesize < size' failed.)

Steps to reproduce

The file I'm trying to typecheck does not compile - it has a kind mismatch in it.

type family ConfigFor (ty :: ScoreType) :: Type where

ScoreType actually has a type parameter, but In this type family signature it has not been added yet. GHC properly reports this error, and HLS does too (when called directly via a shell), but after failing it just endlessly attempts to recompile again.

Include debug information

Here's a log of letting hls run until it arbitrarily crashes with an error to stderr (stack overflow error?).

haskell-language-server-8.8.4: allocatestack.c:384: advise_stack_range: Assertion `freesize < size' failed.
haskell-language-server-wrapper: callProcess: /home/googleson78/.ghcup/bin/haskell-language-server-8.8.4 "-d" "-l" "looping.log" "src/ScoreType.hs" (exit -6): failed

I'm including all of the stdout, the stderr, and the output of -d, as the stack overflow error seems to not be present in the -d output.
looping.log (-d output)
loopingstdout.log
loopingstderr.log

Thank you for the issue report! It will be also great if you can also provide some reproduction.

It is very similar to #429, it involves using compiler plugins and building hls from source in the machine is using it served as workaround

[googleson78]

Same issue with an hls built from master (currently d60dee0)

[googleson78]

I'm not sure if this is a repro for the same thing, but I got this while trying to slim down my original reproducer - https://github.com/googleson78/repro1638

It doesn't loop forever, but it does loop a few times, so maybe it just doesn't run out of space due to the fact that this repo is a lot smaller compared to the other?

In there, I don't get any errors reported in my lsp client (nvim + LanguageClient-neovim). I would expect to get the error that ghc reports.
