Comment (by Phyx-):

 Hi, Thanks for the report. I have completely missed this.

 Unfortunately this repro is way way to large. I'm even having trouble
 reproducing it from the released `8.0.1` due to all the dependencies
 required for that package.

 Does your project contain any C sources? Can you try and make a repo with
 a smaller dependency chain? one without the need of `old-time` would be
 especially great since there are a few issues compiling that and GHC 8.

 Likely the segfault is coming from one of your dependencies.
