The ICE is from running rustc --version?

[yongqli]

No, it is from trying to compile a file that has errors. When the error is fixed the ICE disappears.

[apasel422]

Could you post the contents of the file?

[emoon]

@yongqli could you post the content of the file? Otherwise it will be very difficult to track down the problem.

[apasel422]

@yongqli Is the code that causes this still available?

[yongqli]

Sorry, no :(.
