error: the compiler unexpectedly panicked. this is a bug.

Backtrace

[lopopolo]

Not sure if related, but I also filed #135564 (and #135566 because I accidentally closed #135564)

[cyrgani]

Probably a duplicate of #135515, which is fixed in the latest nightly.

Thanks for opening an issue!

PR #135520 has already fixed this problem, and is available in today's nightly, so we can close this. Feel free to reopen if it happens again.
