Unfortunately I could not reduce the size further, if I remove larger blocks the fault disappear and I couldn't be bothered to figure out what exactly can be removed by removing single bytes:)
The fault does not appear in the playground. Possibly windows related?

The used rustc version:
rustc 1.7.0-nightly (110df04 2015-12-13) (MSVC edition)

It is running on windows 8.1 64bit.

cc #23344

[AerialX]

Related to #23344

When writing data, we don't handle the case where a multibyte character straddles calls to write. Like the reading case, this could be alleviated with a 4-byte buffer for unwritten-but-valid-utf8 characters.

Regardless of a proper approach to all of #23344, dealing with this case would be a good interim fix.

[elszben]

This code crashes with the same error.

    let v = vec![255u8; 5000];
    let s = String::from_utf8_lossy(&v);
    // println!("Len {}", s.len());
    println!("{}", s);

[retep998]

I suppose it was inevitable that someone would run into this edge case of how we handle unicode in the console on Windows.

[alexcrichton]

I believe that this is an unfortunate result of #23344, so I'm going to close in favor of that (as that's the issue at hand here), but thanks for the report!
