Node version (or tell us if you're using electron or some other framework):

node v.6.9.1

ShellJS version (the most recent version/Github branch you see the bug on):

(most recent)

Operating system:

windows 10

Description of the bug:

// simple c++ files to compute factorial
// with prints to stderr & stdout, and exit codes
//
#include <stdio.h>
#include <stdlib.h>

int factorial(int n)
{
if (n == 1)
return 1;
else
return n*factorial(n-1);
}

int main(int argc, char *argv[]) {

fprintf (stderr, "test");

if ( argc != 2 ) {
	fprintf (stdout, "0\n");
	exit(1);
}else {
	fprintf (stdout, "%d", factorial( atoi(argv[1]) ) );
	exit(0);
}

}

Example ShellJS command to reproduce the error:

// as simple as this ...
//
var shelljs = require('shelljs');

shelljs.exec('./factorial.exe ' + 5, function(code, stdout, stderr) {
console.log('code: ' + code);
console.log('stdout: ' + stdout);
console.log('stderr: ' + stderr);
});
