Cargo run does not display segmentation fault information

[isaacg1]

With the following program, which causes a segmentation fault by allocating too much on the stack:

fn main() {
    println!("Hello world");
    let memo = [[[0; 255]; 255]; 255];
}

Running cargo build followed by executing the binary prints: Segmentation fault (core dumped).
In contrast, running cargo run gives no textual indication of the failure. The output displayed is:

    Finished debug [unoptimized + debuginfo] target(s) in 0.0 secs
     Running `./three`

This is using either of cargo 0.16.0 and 0.15.0 on Ubuntu Linux 14.04

Thanks for the report! Cargo just calls exec, however, on the binary ./three. In that sense it's up to your shell to report segfault information, but this is likely being swallowed by rustup, so I'm going to close in favor of that issue.
