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.

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.
