panic compiling pkg-config

[scottlamb]

The latest nightly panics when compiling the latest version of pkg-config (on a Raspberry Pi 2, running Raspbian Jessie).

I tried this code:

https://github.com/alexcrichton/pkg-config-rs
at master tip (commit 4e563eb953b4ee8c1e0a06defd49f3c1a803081f).

I expected to see this happen: a successful build.

Instead, this happened: a compiler panic. Here's the lowlight:

thread 'rustc' panicked at 'assertion failed: eps.windows(2).all(|w| w[0].cmp(self, &w[1]) != Ordering::Greater)', /buildslave/rust-buildbot/slave/nightly-dist-rustc-cross-host-linux/build/src/librustc/ty/context.rs:1525
