Installation fails on OS X 10.9.3 with Go 1.3 about goncurses HOT 11 CLOSED

Looking at the panic, this may be a bug in Go itself...have you tried compiling 
any other programs that require cgo with Go 1.3?

It looks like cgo works in simple cases.  Test case borrows from cgo's 
introductory documentation:

$ cat rand/rand.go
package rand

/*
#include <stdlib.h>
*/
import "C"

func Random() int {
    return int(C.random())
}

func Seed(i int) {
    C.srandom(C.uint(i))
}

$ go install rand

$ cat rand_print.go
package main

import (
"fmt"
"rand"
)

func main() {
  fmt.Printf("rand %d\n", rand.Random())
}

$ go run rand_print.go
rand 1804289383

I admit, this is a strange error. I don't really have a place to start on 
diagnosing this issue as none of the above errors relate directly to the 
library and I don't have access to a Mac for testing. Posting on mailing list 
to see what I can turn up.

Could you try to compile a simple cgo example with a declared Go type for a C 
type? Specifically, with a C struct type.

I get the same behavior on a completely different project. Perhaps this gives 
some clue?
 Same version of OS X 10.9.3

It was suggested on the mailling list that this could possibly do to libraries 
not being updated to Go 1.3. You can try go install -a or deleting 
$GOPATH/{bin,pkg} to clear out old libraries.

Replying to #4 (above) I got enough time to finally finish an example of a 
declared Go type using a C structure and calling native functions.

This may be related to Issue 19: 
https://code.google.com/p/goncurses/issues/detail?id=19&can=1

Try updating to Go 1.3.1 and see if it fixes the problem.

Works under 1.3.1

$ go version
go version go1.3.1 darwin/amd64

Needs export CC=clang.
