DO NOT MERGE (yet): Enable `-Zdrop-tracking` by default by eholk · Pull Request #97334 · rust-lang/rust

eholk · 2022-05-23T20:07:54Z

This is not quite ready to merge yet because we still need fixes for a couple of issues (See #97331 for details), but we can probably go ahead and kick off a crater run to see if there are any additional regressions we don't know about yet.

Huh, that's weird that we're suddenly getting a bunch of new test failures. I wonder what changed in this code? Maybe #101692 had some effect here?

cjgillot · 2023-02-25T16:57:15Z

#101692 has duplicated each generator test case to have the 3 variants (no drop tracking, drop tracking, and MIR drop tracking). This may be where the errors come from.

☔ The latest upstream changes (presumably #110252) made this pull request unmergeable. Please resolve the merge conflicts.

Swatinem · 2023-09-24T12:47:51Z

I believe this can be closed now that #107421 has landed?
