Issue
mirai panics (in rustc code) when checking a crate of mine: https://github.com/osa1/tiny
Steps to Reproduce
Just build using the described workflow in MIRAI README file.
Expected Behavior
I'd expect the build to finish without panics.
Actual Results
It panics. Error with backtrace: (I just realized there are more panics if I let the build finish, I included all below)
Build failures, with backtraces
Compiling nix v0.19.1
Compiling syn v1.0.60
Compiling sct v0.6.0
Compiling tokio v0.3.7
Compiling webpki v0.21.4

I am actively working on these issues. The rust compiler's tendency to panic for obscure reasons certainly does not help. For the time being I am focusing exclusively on the Diem crates. You can get more traction if you first build your crate with the normal compiler and then build just your crate with MIRAI. (Touch the lib.rs of your crate. Be sure to use the same Rust flags. Remember to set RUSTFLAGS="-Z always_encode_mir in your environment.)
