How to fix crashing C in Windows 8.1?

问题

I'm using Code Blocks with MinGW Gcc. Compile build works fine but it crashes when I execute it to run:

main.c:

#include <stdio.h>
#include <stdlib.h>
#include <vlc/vlc.h>
#include <vlc/libvlc.h>
#include <windows.h>

int main(int argc, char **argv) {
    libvlc_instance_t *vlc;
    vlc = libvlc_new (0, NULL);
    return 0;
}

Build log:

-------------- Clean: Debug in rtsp (compiler: GNU GCC Compiler)---------------

Cleaned "rtsp - Debug"

Process terminated with status 0 (0 minute(s), 1 second(s))

Why is this happening?

How can I fix this?
