Simon, I believe you will need to rebase over https://gitlab.haskell.org/ghc/ghc/-/commit/604eb43c2fec19ba605176744a6854be... to fix a bug I mistakenly introduced that caused Hadrian test output to be suppressed. Best, Sam

Hi Simon, I think you encountered https://gitlab.haskell.org/ghc/ghc/-/work_items/27780. It's already fixed in master, so if you rebase, you should get proper test output again. Cheers, Simon Am Di., 8. Sept. 2026 um 18:39 Uhr schrieb Simon Peyton Jones via ghc-devs <ghc-devs@haskell.org>:

Friends

On https://gitlab.haskell.org/ghc/ghc/-/merge_requests/16447 I'm getting a mysterious failure in the testsuite. The error, below, is not very informative.

Can anyone help, please?

Thanks
