Cannot build with -Z instrument-coverage

[eutampieri]

I tried to compile this crate with RUSTFLAGS="-Z instrument-coverage" cargo build.

I expected to see this happen:

The crate builds, possibly with LLVM instrumentation

Instead, this happened:

The crate doesn't build at all

I'm building with a docker image generated using this Dockerfile

Any luck resolving or working around this @eutampieri?

I'm hitting the same error elsewhere and struggling to find a resolution:

[eutampieri]

@ansscfc no, not at all. In facts, I’d just reported a bug and never looked into it with effort.

[Neopallium]

FYI, I was able to get coverage to work by using the Circle CI rust image cimg/rust:1.60.0 and installing rust nightly. Also image rust:bullseye seems to work too.

[eutampieri]

Thanks, now that it’s on stable it’s been probably fixed
