• User reports hls works fin in a new simple project and this one has template haskell which works with 8.10

[jneira]

It is reproduced with

1. cabal init with cabal 3.4
2. add aeson as dependency to build-depends in the cabal file
3. open the project in vscode with code .

[anka-213]

I wonder if it's related to this change: #1649 (comment)

I never managed to figure out how, when and if initLoaderState is supposed to be used in ghc-9.0.

[jneira]

As confirmed by the original reporter, the segfault was caused by using the precompiled hls binary (ubuntu-18.04/debian 10) in a machine with debian 9. The workaround has been built hls from source in the target machine.
Not sure if we can do much more in our end.

Maybe we could provide binaries for the different linux versions, but it would make the releases and the distribution more complex.

It is related with the problems in our ci when github bumped up the linux latest version to ubuntu-20.04/debian 11: #1723

[AxelUlmestig]

I had a similar problem on Ubuntu 20.04, I would get a segmentation fault from HLS when using Hasql-TH. Everything else worked fine.

Building HLS from source solved the issue.

To install HLS from source run:

./cabal-hls-install hls-8.10.7
