#if defined(_DEBUG) || defined(DEBUG) // In VC++ compilers, the macro is "_DEBUG", not "DEBUG".
// If set memcheck = true, the program will be vitally slow since it will log all malloc() / realloc() / free() calls to find the cause of memory leak.
// For normal debug we set memcheck = false.
// Please set memcheck = true if you want to test the cause of memory leaks.
