"No counters provided the source_hash for used function" when compiling with -Z instrument-coverage

Will try to put together a minimal example, but it's currently occurring with https://github.com/iotaledger/wallet.rs

The issue #85213 has some minimal code. (And I think, its a duplicate)

It first occurs with the nightly-2021-05-08-x86_64-unknown-linux-gnu toolchain. nightly-2021-05-07-x86_64-unknown-linux-gnu still works. I am unsure how to specify the version number correctly, but this is what rustup tells me. (text copied from my comment in the other issue)

If someone wants to do the git bisect:
good: 676ee14, bad: 770792f

[richkadel]

This is a duplicate of known issue reported here: #85081 and the change that caused it was reverted. The next nightly should resolve the problem.

[ririsoft]

I confirm the bug is fixed with

Thanks a lot @richkadel for all your work here !

However I now have a linking with link.exe failed: exit code: 1227 issue:

It only raises when compiling with RUSTFLAGS = "-Z instrument-coverage".

Do you believe this deserve a dedicated bug report or I am doing something wrong here (should use another linker on windows ?), please ?

[richkadel]

@ririsoft - That is definitely a different bug report.

I don't know what that's about. You might try compiling with one of the -Zinstrument-coverage=<value> options, to disable generating coverage for dead code. I don't know if it will make a difference, but I do use weak linkage when creating the function stubs for dead code.

Whatever your results, please report them in a separate issue along with your description above.

Thanks!

[richkadel]

@rajivshah3 - You should be able to confirm with the latest nightly that this issue is fixed. Thanks!

[rajivshah3]

Yep, fixed! Thanks so much @richkadel!
