What did you do?

With the following the contents of /tmp/ice.go (the Go playground rejects it as it doesn't vet):

package main

func main() {
	panic(0)

	x := 0

l:
	for {
		goto l
	}

	_ = x
}

I attempted compilation.

What did you see happen?

Attempting to compile lead to an internal compiler error:

$ go build /tmp/ice.go 
# command-line-arguments
CLOSURE [/tmp/ice.go:13:6:var x int]
<unknown line number>: internal compiler error: assertion failed

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

Fiddling with the panic's placement, the existence of a label and the existence of a declaration which is referenced after the label, only this combination yielded an internal compiler error.

What did you expect to see?

I want to get an executable which immediately panics, not a confused compiler's goodbye.

This is duplicated of #65593

I updated to go1.22.3 linux/amd64 which doesn't ice on the above.
