The test-primops job has started failing due to a link error for the last few days: https://gitlab.haskell.org/ghc/test-primops/-/jobs/2065089 ``` 1 of 1] Compiling Main ( Run.hs, /builds/ghc/test-primops/dist-newstyle/build/x86_64-linux/ghc-9.13.20241214/run-it-0.1.0.0/x/run-it/build/run-it/run-it-tmp/Main.dyn_o ) [2 of 2] Linking /builds/ghc/test-primops/dist-newstyle/build/x86_64-linux/ghc-9.13.20241214/run-it-0.1.0.0/x/run-it/build/run-it/run-it /usr/bin/ld.gold: error: /builds/ghc/test-primops/dist-newstyle/build/x86_64-linux/ghc-9.13.20241214/run-it-0.1.0.0/x/run-it/build/run-it/run-it-tmp/Trampoline.o: multiple definition of 'stg_trampoline' /usr/bin/ld.gold: /builds/ghc/test-primops/dist-newstyle/build/x86_64-linux/ghc-9.13.20241214/run-it-0.1.0.0/x/run-it/build/run-it/run-it-tmp/Trampoline.dyn_o: previous definition here collect2: error: ld returned 1 exit status ghc-9.13.20241214: Uncaught exception ghc-9.13-inplace:GHC.Utils.Panic.GhcException: `gcc' failed in phase `Linker'.

I can't see why this job has suddenly started failing as no configuration or code I can see has changed. The following patch to `test-primops/run-it` allows the link to succeed: ```diff diff --git a/run-it/run-it.cabal b/run-it/run-it.cabal index 536db9f..e5c4071 100644 --- a/run-it/run-it.cabal +++ b/run-it/run-it.cabal @@ -12,7 +12,6 @@ executable run-it main-is: Run.hs cmm-sources: Trampoline.cmm -- silly Cabal doesn't link cmm-sources into executables - ghc-options: Trampoline.cmm build-depends: base, unix, mmap ```
