Description
After updating from 1.13.0 nightlies to 1.14.0, using incremental compilation, my crate does not compile any more. Not sure, how to reduce this to a minimal example yet. A normal, non-incremental build works without problems.
This issue remains after cargo clean and removing the incremental compilation cache directory.
Here is the truncated log of a env RUSTFLAGS="-Z incremental=.cache/ -A warnings" RUST_TEST_THREADS=1 cargo build --verbose:
cat: cat: No such file or directory
