Segmentation fault: llvm::GetElementPtrInst::getGEPReturnType

[xaionaro]

Hello. I've just built fcd and a Go's hello world, and tried to decompile the hello-world with fcd. As result it's a segfault:

$ cat helloworld.go 
package main
import "fmt"
func main() {
        fmt.Println("Hello, world!")
}
$ go version
go version go1.7.4 linux/amd64
$ go build
$ ~/src/fcd/build/fcd hello
