Coverage on stable 1.79.0 fails with : maybe try to call try_normalize_erasing_regions
instead
#125353
Comments
Ok, I have some bad and some good news. The bad one is that this bug is landed in stable 1.79.0 😢 The good one is that I can give you a repo to reproduce it: Clone https://github.com/HorizenLabs/zkVerify , here the follow command reproduce the issue: cargo llvm-cov --all-features --workspace --lcov --output-path lcov.info That's a regression on stable from 1.78 to 1.79 I'm sorry, I know that's a huge but I don't know how to narrow it. |
try_normalize_erasing_regions
instead try_normalize_erasing_regions

@jieyouxu Now that this bug is landed on stable shall not be better to take another look on it? If there's something that I can do let me know. |
I've run into this issue too, exactly the same setup (substrate project, build and test works fine, but coverage build fails with this error) |
cc @Zalathar maybe you have any ideas on how to make the example smaller? |
Does the same issue occur when you do a non-coverage build with Coverage enables that as a side-effect, so this might be a symbol-mangling issue rather than a coverage issue (e.g. see also #116303). |
Yes! If I run with |
I can confirm it too: RUSTFLAGS="-Csymbol-mangling-version=v0" cargo build --release meet the same issue. |
If this is reproducible with |

Could it be #127351 ? - appeared around the same time. |

Unfortunately I cannot provide a minimal example. I meet this issue while I'm trying to run coverage on nightly to experiment on
coverage_attribute
feature on an substrate based project.I've experimented this issue with both
nightly-2024-05-20
andnightly-2024-04-
0`. I cannot bisect on it because the compilation time is too hugeThe good news is that botn
cargo +nightly build
cargo +nightly test
work fine and the issue seams just related to the coverage stuff.Meta
