cvLoadImage causes segfault in a secondary thread (Bug #596)

Can't reproduce on trunk. Tried on Linux:

 1void* func(void*)
 2{
 3    for (int i = 0; i < 1000; i++)
 4    {
 5        Mat a = imread("/home/alex/Desktop/source.png", 1);
 6        //imshow("a",a);
 7        //char c = waitKey(0);
 8        //if (c == 27)
 9        //   break;
10        cout << i << endl;
11    }
12}
13
14int main(int argc, char * argv[])
15{
16
17  pthread_t thread;
18  pthread_create(&thread, NULL, func, NULL);
19  pthread_join(thread, NULL);
20
21  return 0;
22}

and Windows:

 1DWORD ThreadProc (LPVOID lpdwThreadParam )
 2{
 3    for (int i = 0; i < 1000000; i++)
 4    {
 5        Mat a = imread("/home/alex/Desktop/source.png", 1);
 6        //imshow("a",a);
 7        //char c = waitKey(0);
 8        //if (c == 27)
 9        //   break;
10        if (i%1000 == 0)
11            std::cout << i << std::endl;
12    }
13    return 0;
14}

16int main(int argc, char * argv[])
17{
18DWORD dwThreadId;
19HANDLE hThread = CreateThread(NULL, //Choose default security
200, //Default stack size
21(LPTHREAD_START_ROUTINE)&ThreadProc,
22//Routine to execute
23(LPVOID) 0, //Thread parameter

27WaitForSingleObject(hThread, INFINITE);
28return 0;
