Sudden exit in GHCi for FFI code - works when run as executable

Summary

I am integrating a C++ library into a project for musical live coding - so GHCi is always used. My integration works when the project is run as an executable via cabal v2-run but not when run via cabal v2-repl. GHCi exists with exit code 541541187 which corresponds to 0x20474343, which seems to be a fairly common, but unspecific, error code.

Steps to reproduce

The code to reproduce exists here: https://github.com/Zalastax/Tidal/tree/tidal-link/tidal-link ( https://github.com/Zalastax/Tidal/commit/1e5bc9f121abfd2d3c47cb778778b9f7b1dbda9a ). Check out the linked commit, run git submodule update --init --recursive. Go to the tidal-link directory. Run cabal v2-run and observe that it cleanly exits after pressing enter 6 times (there are a few getLine).

$ cabal v2-run
Up to date

"hello"
"Created link"
"gotline"
"Link enabled"
"gotline"
"Created sessionState"
"gotline"
"Now: 690261494419"
"gotline"
"gotline"
"beat: 20.418723"
"gotline"
"Now': 690266558073"
"beat': 27.845418"

Follow up by running cabal v2-repl, call hello (which is IO ()), press enter twice, notice that it crashes.

$ cabal v2-repl

If I instead build a .dll and make my FFI calls towards that .dll, the code does not crash in GHCi. See follow-up commit https://github.com/Zalastax/Tidal/commit/6d3c67124d9f0ac1e183288ceaa954d9b0bc6df6.

Expected behavior

I expect that the program should work both when run as executable and in GHCi.

Environment

• GHC version used:
  GHC 9.0.1 or
