Terraform crashes when using concat with more than two args

[lbernail]

When I try to concat three strings (or vars) in a resource terraform plan crashes
Example:

provider "aws" {
    access_key  = "${var.access_key}"
    secret_key  = "${var.secret_key}"
    region      = "${var.region}"
}

resource "aws_vpc" "main" {
    cidr_block = "${concat(var.vpc_cidr_base,"-","0.0/16")}"
}

Same code with two strings or vars (cidr_block = "${concat(var.vpc_cidr_base,"0.0/16")}") works ok

Version: Terraform v0.2.1
