QtCreator hangs in debug mode on shell command execution

[dbondarevych]

Hi!
I have met a problem with debug mode in QtCreator 2.7.1 based on QT 5.0.2 (64 bit). Linux, Ubuntu.
Here is a simple code to reproduce:

@#include <iostream>
#include <stdlib.h>

using namespace std;

int main(int argc, char** argv)
{
cout << "Before system call..." << endl;

system("pwd"); // Hangs here in debug mode!!!

cout << "After system call..." << endl;

}@

In Run mode, works fine, output is:
Before system call...
/home/...
After system call...

In Debug mode, hangs on system("pwd"), output is:
Before system call...

Project settings:
TEMPLATE = app
TARGET = main
QT -= core gui

SOURCES += ../main.cpp

Please, help to investigate and configure project or environment properly.
