Backtrace

[Voker57]

not reproducible in the nightly

[theemathas]

Presumably fixed by #126068, given the several issues with similar "index out of bounds" symptoms.

Edit: Maybe it's a different issue, given that the error occurred on a stable release?

[lqd]

No it's more a dupe of #118185, and thus fixed by #124227.

[veera-sivarajan]

@rustbot label +A-hir -needs-triage

[lqd]

Since it's already fixed on nightly since a month or so, I'm not sure it's necessary to track this anymore. I'll close this issue as a duplicate. The fix will land on stable in 1.80, in roughly 6 weeks.

Thanks for opening an issue.
