Miri is outdated

[RalfJung]

The Miri on playground is from 2019-11-08, there have been quite a few updates since then.

@Aaron1011 see the build log at https://travis-ci.com/integer32llc/rust-playground/jobs/259856086:

error: failed to run custom build command for `html5ever v0.23.0`

Caused by:

  process didn't exit successfully: `/playground/target/debug/build/html5ever-e09cbe0abacfb0e8/build-script-build` (signal: 4, SIGILL: illegal instruction)

This might have to do with the cfg(miri) in libunwind?

[RalfJung]

This should be fixed by rust-lang/rust#66822

@shepmaster This time the Miri job ran successfully, but on playground it still says "2019-11-08". Any idea why?

[shepmaster]

Looking now, it says 12-04; perhaps just the timing between when it’s built and when the playground downloaded it?

[RalfJung]

Yeah must have been something like that.
