SegFault in OpenCV 2.4.2 and MinGW on WinXP

edit

I am working on a WinXP machine. I downloaded and installed the prebuilt binaries OpenCV-2.4.2.exe.

I am trying to build a very simple program using MinGW:

#include <opencv2/core/core.hpp>
#include <opencv2/highgui/highgui.hpp>
using namespace cv;

int main()
{
    Mat im = imread("lena.png");
    if (im.empty()) {
        return -1;
    }
    imshow("image", im);
    waitKey(0);

    return 0;
}

This is how I am compiling:

g++ loadimg.cpp -I"${OPENCV_DIR}/include" -L"${OPENCV_DIR}/x86/mingw/lib" -lopencv_core242 -lopencv_highgui242 -lopencv_imgproc242 -o loadimg

where OPENCV_DIR is an environment variable that points to OpenCV location:

$ echo $OPENCV_DIR
C:\Program Files\OpenCV\2.4.2\build

It compiles just fine, but I get a segfault when I try to run it:

I am using the the most recent MinGW (mingw-get update && mingw-get upgrade):

$ g++ --version
g++.exe (GCC) 4.7.0

For what it's worth, I can compile and run the above just fine in Visual Studio 10. My problem is using MinGW....

Any help is appreciated
