The following program hangs in Execute.
package main
import (
"text/template"
"io/ioutil"
)
func main() {
t, err := template.New("foo").Parse(data)
if err != nil {
return
}
t.Execute(ioutil.Discard, nil)
}
var data = "{{printf \"%017091901790959340919092959340919017929593813360\" 0}}"
SIGABRT: abort

This reproduces the hang.
package main
import "fmt"
func main() {
fmt.Printf("%017091901790959340919092959340919017929593813360", 0)
}
