            Bug ID: 24976
           Summary: Data from SBProcess::PutSTDIN appears in
           Product: lldb

Python script with PutSTDIN and GetSTDOUT test

When I use the function SBProcess::PutSTDIN to put data into process' STDIN,
the entered data then appears when I get the process' STDOUT.

I attached C++ test program which reads a string (x) and then outputs "stdout:
<x>" and a python script that shows that the stdout contains both "stdout: <x>"
and x. The sleep is there to wait for the program to output data.

// C++ program:
#include <iostream>

using namespace std;

int main(int argc, char** argv)
    string a;
    cin >> a;
    cout << "stdout: " << a << endl;

    return 0;

After I run this program with input "test", it should output "stdout: test".
But when I put "test" to the process via PutSTDIN, the GetSTDOUT contains both
"test" and "stdout: test".

Am I doing something wrong?
