ICE when compiling with -Z ast_json

[schmee]

Compiling https://github.com/schmee/rust/blob/counted-set/src/libcollections/counted_set.rs on Windows 7 with rustc counted_set.rs -Z ast-json or rustc counted_set.rs -Z ast-json-noexpand results in the following ICE:

$ rustc counted_set.rs -Z ast-json

note: the compiler hit an unexpected failure path. this is a bug.

Could you provide a gdb stack trace as well?

[schmee]

Sure! First time using gdb, I hope this is correct:

On windows I've seen I/O errors when you're reading into a very large buffer, so this may be triggering errors when you're writing a very large buffer. Does this program fail for you?

use std::io::stdio;

fn main() {
    let mut out = stdio::stdout();
    out.write(['a' as u8, ..128 * 1024]).unwrap();
}

[schmee]

Yes, yes it does!
