Hello,

I'm fine with reverting for now. But could you give me a way to reproduce this error?

I've not seen crashes on either linux and windows in various configs.

I suspect that Simon is building with SplitObjects enabled. To be honest, I would really like to remove this feature; SplitSections is better in nearly every regard. However, we have been stalled since SplitSections doesn't quite work yet on Windows (or, IIRC, the toolchain is prohibitively slow when it's used). I believe Tamar was working on fixing this.

SplitObjects has been off in favor of SplitSections on Windows since Aug. https://github.com/ghc/ghc/commit/23774c98f1368b41515cbd5223b87ea6dbf644e1 SplitObjects is not usable on Windows anymore so it was disabled https://ghc.haskell.org/trac/ghc/ticket/15051

Cheers,
