I think this happens when miri tries to run with an outdated std.

I have a locally build toolchain with miri, and sometimes after reinstalling/updating the toolchain (x.py install), I think miri does not catch that it was updated and would have to recompile its std.
cargo miri run will panic then:

error: the compiler unexpectedly panicked. this is a bug.

note: we would appreciate a bug report: https://github.com/rust-lang/rust/issues/new?labels=C-bug%2C+I-ICE%2C+T-compiler&template=ice.md

note: rustc 1.71.0-dev running on x86_64-unknown-linux-gnu

Yeah, so running cargo miri setup of a different toolchain (e.g. nightly) and then running setup again for the locally installed toolchain is a workaround.

See rust-lang/rust#110572 (comment)

well, this is not really a problem of stage x vs stage y since it's always this stage in my case, but the underlying issue (different host compilers) might be the same as this is also the case for different stages

could miri compute a checksum of its own binary and save/check that in the std it prepares to know if it needs to rebuild?

@RalfJung

So to be clear, this is from running cargo miri yourself, in a locally linked toolchain?

We have a similar issue inside rustc bootstrap itself, where x.py test miri fails because the toolchain doesn't get rebuilt as it should. That one could probably be resolved by hooking into the bootstrap logic that clears sysroots.

But fundamentally this is not just a Miri issue, it also affects rustc: we hash the compiler channel and version into the sysroot to check for rebuilds (and rustc does that for its incremental cache), but for local builds that is just dev and so we don't notice when the version changes. (Which is basically what @saethlin referenced above, so Cc rust-lang/rust#76720.)

exactly 🙂

I think the exact same issue would arise if you did cargo run with locally built toolchains (on a crate with some dependencies, and after touch src/lib.rs or so to make rustc actually do something), so trying to work around this on the Miri doesn't seem like the right approach.
