kotlinlang

hi, we recently synced <https://github.com/krzema12/kotlin-python|our fork> with JetBrains/kotlin's master, and we randomly get <https://github.com/krzema12/kotlin-python/runs/4393690680?check_suite_focus=true|such failures (see the Build step)> when building the repo - *details in the thead*.
Are you aware of any issue that still persists on main repo's master or has been already fixed? not sure if it's worth syncing with main repo now, or wait

On which branch from origin kotlin did you rebase? And on which commit in this branch?

this is the merge commit: <https://github.com/krzema12/kotlin-python/commit/d0dd070c2dc3a4660ab416cbb07a18b694ddd15c>
so we merged from tag `v1.6.0` . Source commit: <https://github.com/krzema12/kotlin-python/commit/829d1d887636689955b56beebdbb8725e908ef0f>

Sorry, completely forgot about this thread

This issue is very strange (especially because you say those failures are flaky). Project in `master` branch almost always can be compiled and all tests are passed, and for release branches there can not be a situation that compiler build fails (and commit you rebased on is from release branch)

I can suggest only to sync with 1.6.10 or with fresh master
