What's the content of hello.rs?

Is this only happening on a recent nightly? Or did it happen before?

Does stable produce the same error?

[xianghx]

stable ok.
maybe 2007-10-14 nightly ok.

then, rustup update nightly , doesn't work.

hello.rs
fn main() {}

This looks like something wrong in your build environment, not with pulldown-cmark itself. #42239 is a similar error. Are you able to compile other programs?

see pulldown-cmark/pulldown-cmark#101

[oli-obk]

Have you tried updating nightly again?

[xianghx]

rustup update nightly
info: syncing channel updates for 'nightly-i686-unknown-linux-gnu'

nightly-i686-unknown-linux-gnu unchanged - rustc 1.22.0-nightly (4c053db 2017-10-22)

[Mark-Simulacrum]

@alexcrichton Possibly related to the recent breakage of 32-bit cross compiles on nightlies?

[alexcrichton]

Seems quite likely, yes, that this is #45500
