gccgo compiled programs crash when printing syscall errors

steps to reproduce:

$ gccgo -x go - << EOF
package main

import (
    "fmt"
    "syscall"
)

func main() {
    fmt.Println(syscall.Errno(1))
}
EOF
$ ./a.out

expected behavior:

"operation not permitted" is printed

actual behavior:

"SIGABRT: abort" and some other information is printed

additional information:

because linux == glibc, right?
