如何修复Windows 8.1中的崩溃C？

我正在用MinGW Gcc使用代码块。 编译构build工作正常，但是当我执行它运行时崩溃：

main.c中：

#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; } 

生成日志：

为什么发生这种情况？

我怎样才能解决这个问题？
