macOS builds appear broken #331

Open bnaecker opened 1 day ago

bnaecker commented 1 day ago

Some of the recent bot PRs for updating dependencies have failed on macOS. Here is a link to the error I see for all of them. That points to the file /usr/lib/dtrace/tcp.d, which is a system-provided D file with what looks like definitions of a bunch of TCP-related types, presumably to support tracing TCP connections and traffic. The error is complaining about an "invalid type identifier" for a struct tcpcb*. That type is defined just below the line where the failure appears, so I'm not sure what the issue is.

I should also note that this is failing on macOS 14.7.1. I am running 14.6.1 locally, and I see no such failure.

I pushed a test commit in #332, which just prints the contents of the offending D file to compare. Of course, that did not fail, and also the setup CI job claims it's running on macOS 14.7, which is different than the failed runs.

Ok, it appears that (1) the issue occurs only with macos 14.7.1, and not 14.7, and (2) it is entirely unpredictable which runner we get for any particular CI job.
