GHC Quickest flavour segfaults when it compiles input program

Summary

GHC 8.11.0 (9668781a) compiled with the Quickest flavour segfaults during compilation of optparse-applicative-0.15.1.0. It exits without any error message, just segfaults.

Steps to reproduce

I created a tiny sample project on github: https://github.com/csabahruska/ghc-bug-sample/tree/17fb252158ba6826307691cef0edfd43893fa8ab

1. compile GHC with the Quickest flavour
2. clone the ghc-bug-sample repository
3. set the path in stack.yaml last line to the compiled GHC Quickest
4. run ./compile.sh

Expected behavior

It should build the project including optparse-applicative. Instead it stops after the Options.Applicative.Help.Core module.

optparse-applicative> [ 7 of 16] Compiling Options.Applicative.Common
optparse-applicative> [ 8 of 16] Compiling Options.Applicative.Help.Core
