Does anyone have context on this intermittent CI failure in rust tests?:

thread panicked while panicking. aborting.
error: process didn't exit successfully: `/home/travis/build/pantsbuild/pants/src/rust/engine/target/debug/deps/process_execution-3457b23e8126720e ` (signal: 4, SIGILL: illegal instruction)
Pants rust test failure

I don’t have context, but https://github.com/pantsbuild/pants/pull/6060 should help us get context 🙂
