What did you do?

$ go build ./...
./b/b.go:23:18: internal compiler error: missing wrapper for b.connContext

See https://github.com/misha-ridge/go-compiler-internal-error for the reproducer.

The error disappears if the files are moved into one package, so I can't provide go.dev/play link.

What did you expect to see?

The code compiles.

What did you see instead?

This appears to be already fixed on HEAD. I confirmed that it fails with 1.21rc2.

CC @randall77 @mdempsky @cuonglm just in case.

@ianlancetaylor ianlancetaylor closed this as not planned Won't fix, can't repro, duplicate, stale Jun 27, 2023

Thanks. Will this be backported to 1.21 branch?

It will be included in 1.21 branch, as 1.21 is not released yet, so there's nothing to be backported.
