Issue Description

Maybe it is just some false positives but I get Conditional jump or move depends on uninitialised value(s) errors with the following code and latest librealsense:

// License: Apache 2.0. See LICENSE file in root directory.
// Copyright(c) 2017 Intel Corporation. All Rights Reserved.

#include <iostream>
#include <librealsense2/rs.hpp> // Include RealSense Cross Platform API

// Capture Example demonstrates how to
// capture depth and color video streams and render them to the screen
int main(int argc, char * argv[]) try
{
    rs2::log_to_console(RS2_LOG_SEVERITY_ERROR);

    // Declare RealSense pipeline, encapsulating the actual device and sensors
    rs2::pipeline pipe;

    // Start streaming with default recommended configuration
    // The default video configuration contains Depth and Color streams
    // If a device is capable to stream IMU data, both Gyro and Accelerometer are enabled by default
    pipe.start();

    rs2::frameset data = pipe.wait_for_frames();    // Wait for next set of frames from the camera

    return EXIT_SUCCESS;
}
catch (const rs2::error & e)
{
    std::cerr << "RealSense error calling " << e.get_failed_function() << "(" << e.get_failed_args() << "):\n    " << e.what() << std::endl;
    return EXIT_FAILURE;
}
catch (const std::exception& e)
{
    std::cerr << e.what() << std::endl;
    return EXIT_FAILURE;
}
