cargo_binary() SIGBUSes on non-existing binary target

• assert_cli version: v0.5.4
• Rust version: rustc 1.23.0-nightly (2be4cc040 2017-11-01)
• OS and version: Darwin Marv.local 16.7.0 Darwin Kernel Version 16.7.0: Thu Jun 15 17:36:27 PDT 2017; root:xnu-3789.70.16~2/RELEASE_X86_64 x86_64

Issue

If function cargo_binary() get called with the binary name that doesn't exist in the package, the test execution crashes with SIGBUS, like this:

error: process didn't exit successfully: `/Users/behnam/.../target/debug/deps/test_cargo_binary-f8993162279cd841` (signal: 10, SIGBUS: access to undefined memory)

Repro

#[test]
fn test_1() {
    Assert::cargo_binary("NONEXISTING_NAME").unwrap();
}

Uh... this is actually an issue with Rust Nightly. Reported here: rust-lang/rust#45731
