Fix test regression in Rust 1.15 #6

Closed mbrubeck closed 7 years ago

mbrubeck commented 7 years ago

Fixes rust-lang/rust#38974.

The tests just use $OUT_DIR as a place to write temporary files. An alternate fix would be to use the tempdir crate to create a directory instead.

The Travis build is failing on beta and nightly with what I believe is an unrelated error. I can't reproduce that error locally in either beta or nightly.

Yeah, I'm not entirely sure what's going on with the Travis tests. I re-ran them a few times and they didn't pop up, which is certainly worrying but I can't think of any good reason for the given errors to occur with the changes you've submitted and not elsewhere.
