When trying to build a project with matrixmultiply as a dependency, I get a compiler panic.

On my machine (running Linux Mint 18.2) this is sufficient to reproduce it:

$ cargo new --bin debug
     Created binary (application) `debug` project
$ cd debug
$ echo 'matrixmultiply = "0.1.13"' >> Cargo.toml 
$ cargo build --verbose
    Updating registry `https://github.com/rust-lang/crates.io-index`
   Compiling matrixmultiply v0.1.13

note: the compiler unexpectedly panicked. this is a bug.

error: Could not compile `matrixmultiply`.

Caused by:

$ rustc --version

I expected to see this happen: The project builds.

Instead, this happened: The compiler panics.

Rerunning the command that causes the crash in verbose mode, with backtrace enabled, gives:

Looks like a duplicate of #43357.

You are using an old nightly compiler (2017-07-25 - that's from a month ago). Updating to the newest nightly should fix your problem.
