It crashed again when retrying.

Nothing should have changed between the two merges except for the branch being merged.

Unsuccessful merge is Make pest no_std compatible. by 01mf02 · Pull Request #498 · pest-parser/pest (github.com).

I'm going to send a support request to GitHub, to see if they can answer this.

Is there a better place to report this than here?

In doing some research on similar errors, it seems that PR's with edits to the workflow file are a common source of errors.

In my case, indeed the PR in question has edits to the workflow file.

Yes, I know about that issue. The limitation with GitHub workflows is not going to be fixed. Sorry.

The pull request that @CAD97 was trying to merge did not change any workflow files. That’s what confused me, and prompted a Support request.

A new PR crashed Add Vector to projects using Pest by lucperkins · Pull Request #487 · pest-parser/pest · GitHub and its tiny, but adding new project using pest in readme by mitnk · Pull Request #511 · pest-parser/pest · GitHub which is nearly identical in content merged fine....
