Hello, Something weird might be going on with the macOS 12 x86_64 buildbot....
Two builds of the same latest Rust fail with completely different errors: 1. https://build.macports.org/builders/ports-12_x86_64-builder/builds/26275/steps/install-port/logs/stdio 2. https://build.macports.org/builders/ports-12_x86_64-builder/builds/26314/steps/install-port/logs/stdio Run #1 fails signal 6 (SIGABRT?): rustc exited with signal: 6 Did not run successfully: signal: 6 error: could not compile `openssl-sys` Run #2 fails due to missing object file (maybe the process got sig'd mid-run before it could write out the object file?): error: could not write output to /opt/local/var/macports/build/_opt_bblocal_var_buildworker_ports_build_ports_lang_rust/rust/work/rustc-1.60.0-src/build/x86_64-apple-darwin/stage2-tools/x86_64-apple-darwin/release/deps/rayon_core-9641c1e2ac352716.rayon_core.ce832f4d-cgu.2.rcgu.o: No such file or directory error: could not compile `rayon-core` due to previous error Either way, something odd is happening. Maybe the machine should have some diagnostics run on memory and CPU.
