Encountered error `Unimplemented` selecting `Binder(...)` during trans trying to get coverage #52478

mbr · 2018-07-18T08:35:32Z

I have been trying out both cargo-kcov and cargo-tarpaulin and seem to keep running into the same compiler panic.

From cargo kcov on stable:

error: internal compiler error: librustc/traits/trans/mod.rs:68: Encountered error `Unimplemented` selecting `Binder(<core::char::DecodeUtf16<<std::vec::Vec<u16> as core::iter::IntoIterator>::IntoIter> as arbitrary::traits::Arbitrary>)` during trans

A quick search revealed similar error messages in #43924 and #40247, though those might be unrelated.

BlinkyStitt · 2018-10-21T00:10:54Z

I was trying to use cargo-tarpaulin and proptest together and just ran into this on the latest nightly

svenstaro · 2018-11-13T19:51:54Z

Same observation here when using proptest and cargo-tarpaulin.

I can produce a full stack trace if that is helpful.

Out of curiosity, I tried cargo tarpaulin on the proptest (0.8.7) codebase, and it failed in the same way recrypt-rs was failing.
Here is a full stack trace

note: the compiler unexpectedly panicked. this is a bug.

note: we would appreciate a bug report: https://github.com/rust-lang/rust/blob/master/CONTRIBUTING.md#bug-reports

note: rustc 1.31.0 (abe02cefd 2018-12-04) running on x86_64-unknown-linux-gnu

note: compiler flags: -C debuginfo=2 -C incremental -C relocation-model=dynamic-no-pic -C link-dead-code -C opt-level=0 --crate-type lib

note: some of the compiler flags provided by cargo are hidden

I tried cargo tarpaulin and cargo coverage on a couple other projects that use proptest, but all failed in the same way.
Does anyone have an example repo that uses proptest and can get coverage results?

cyplo · 2018-12-23T11:05:45Z

I recently ported a codebase from quickcheck to proptest, it had tarpaulin before for code coverage set up and working, porting to proptest made the build fail with the same ICE as above.

xd009642 · 2019-01-18T21:50:55Z

Someone on my tarpaulin tracking issue for this xd009642/tarpaulin#161 mentioned it goes away if they remove -C link-dead-code from the options tarpaulin uses to build the tests. They also got results by removing that option (although that impacts the accuracy of coverage results).

jix · 2019-01-19T08:42:45Z

For everyone ending up here trying to use proptest and tarpaulin together: the workaround I described in xd009642/tarpaulin#161 only disables dead code generation for the proptest dependency, which fails to compile with -Z link-dead-code. In my tests so far that doesn't impact the coverage accuracy of the main crate being tested. This is different from disabling dead code generation globally, which, as @xd009642 correctly points out, gives very inaccurate coverage data.

boustrophedon · 2019-01-25T23:39:44Z

I just encountered this trying to get code coverage set up as well. The easiest way to reproduce this is simply to clone the proptest crate directly and run RUSTFLAGS="-C link-dead-code" cargo build

jethrogb · 2019-03-18T18:04:16Z

See reduced test case in #58375 (comment)

jonas-schievink · 2019-03-20T10:09:13Z

Closing in favor of #58375, which has a small reproduction and is nominated for discussion
