Thanks for digging into this! I had done a little but didn't get nearly as far. I am happy I can just ignore it and the problem will resolve itself. ;) While I have the attention of folks who might be interested in CI failures, let me hijack the thread for a moment: has anybody figured out why macOS jobs sometimes time out after 6 hours? I assume that is an Actions limit, and something is just hanging. It sometimes hits osx-reftable[0], but sometimes osx-clang[1] and osx-gcc[2]. I've seen it on my builds and some on git/git (the last one is from git/git). It's hard to tell which test is hanging, because the output only shows the finished tests. I tried running them without "prove" and doing it one-by-one, but then the hang doesn't seem to occur (so presumably it's a race under load). I tried comparing the list of tests reported as finishing versus the total list, but there was nothing enlightening. It's all stuff in t9xxx, which you'd expect to be running near the end anyway (and it feels like if there was _one_ test hanging, we should finish everything else, since we run with some parallelism). So it's almost like a bug in "prove" or something. But AFAIK it just started happening in the past month or two. -Peff [0]: example run: https://github.com/peff/git/actions/runs/8107092556/job/22158038562 [1]: example run: https://github.com/peff/git/actions/runs/8091601551/job/22110929146 [2]: example run: https://github.com/git/git/actions/runs/8273234891/job/22636626511
