Compiler error while building matrixmultiply 0.1.13

I tried to compile a project having matricmultuply in its dependencies using rust 1.20 nightly

This happened:

   Compiling matrixmultiply v0.1.13
error: internal compiler error: /checkout/src/librustc/infer/mod.rs:573: Encountered errors `[FulfillmentError(Obligation(predicate=Binder(TraitPredicate(<K as kernel::GemmKernel>)),depth=0),Unimplemented)]` resolving bounds after type-checking

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

note: we would appreciate a bug report: https://github.com/rust-lang/rust/blob/master/CONTRIBUTING.md#bug-reports

note: rustc 1.20.0-nightly (afe145d22 2017-07-23) running on x86_64-unknown-linux-gnu

I believe this is a duplicate of #43357.
