Okay, so I confirmed that 3.12 branch works fine. I also bisected `master` and tracked it down to #9565. (Which @alt-romes already guessed on Matrix.) We're now trying to figure...

(copied from Matrix) I vaguely recall some early Unixy tool (possibly `mh`) where `@` was a symlink in every directory pointing at a central resource, for convenience. Would it be...

The nightly also works fine; instructions for getting it are in the README.

Note: this ticket is mostly to make it more discoverable than the discussion in the [past](https://hackmd.io/c1yOln1fR_K5WiEhhPsUlQ?both) [two](https://hackmd.io/DZOyLXrkQ7mev3148N0Mbw) cabal calls. Also, I am unlikely to be involved in implementation, as while...

@ulysses4ever, can you arrange for ghc to be run at a high enough verbosity that it tells us what gcc command line it's using? (I don't know how hard this...

I'm trying to build this locally so I can try bisecting ghc, and getting an error: ``` hilfy «cabal:ci-ghc-9.10¤@1ad7e5b58» Z$ cabal build all -w ~/Sources/ghc/_build/stage1/bin/ghc Warning: this is a debug...

This is exactly ghc-9.10-alpha3, but I'll need it to work for random commits in order to try to bisect it.

Okay, I have confirmed that the test fails on ghc `master` and `ghc-9.10` branches locally, and will bisect from `c18658545ce45254a4679c13de5dcc56a4c8373f` after verifying that that commit (base of `ghc-9.8` branch) succeeds...
