Channel panic

[quarnster]

This is a minimal repro of the convertI2V(interface{}, *testing.T) issue mentioned in #48

package main

import "fmt"

func main() {
    type T struct {
        signal chan interface{}
    }
    var t = &T{make(chan interface{})}
    go func(t2 *T) {
        t2.signal <- t2
    }(t)
    t3 := (<-t.signal).(*T)
    fmt.Println(t3)
}
