What did you do?

During refactor I added a panic() to be sure that I was fixing that later. Then compilation failed
See the stripped down code in attached zip (see first comment)

What did you see happen?

$ go build
github.com/user/some/jaccount
CLOSURE [/int_compile_err/jaccount/mailbox.go:52:22:var jmbs github.com/user/some/jaccount.JMailboxes]
: internal compiler error: assertion failed

Please file a bug report including a short program that triggers the error.
https://go.dev/issue/new

What did you expect to see?

I would expect it to compile just fine or give a compile error.

I uploaded the correct zip file. I forgot the recursive flag in the initial upload.

It seems to me this is duplicated of #65593.

@ArnoSen Could you please trying gotip and see if the issue were fixed?

Since you did not post any code nor github repo, we could not reproduce and verify the issue.

I was pointed out that maybe I did not invoke gotip correctly. (actuall it is the first time I use it).
When I do it like this, there is no error:

me@pc:~/personal/go/int_compile_err $ gotip build
me@pc:~/personal/go/int_compile_err $
