Segfault while compiling unicode-xid on Raspberry Pi 3

[krumberg]

Summary
When I try to install cargo-run-script using the stable (or unstable) toolchain I get a segfault.

The issue occurs on arm v7l (Raspberry Pi 3, Raspbian Stretch), but not on x86_64.

Probably the same as #62896
It's fixed in nightly builds.

I wiped my rust installation and tried to install nightly, but it fails

If you require these components, please install and use the latest successful build version,
which you can find at https://rust-lang.github.io/rustup-components-history.
After determining the correct date, install it with a command such as:
rustup toolchain install nightly-2018-12-27

@krumberg it's rust-lang/rustup#2074
You can try adding --force to your command until Rustup fix is released.

Thanks! It finally worked
