（configuration file）に以下の WARNING_FILTER ルールを追加してください。
WARNING_FILTER += discard class="Double Initialization" |
CodeSonar ships with library models that allow it to functions such as Win32 InitializeCriticalSection() that initialize a dynamic object. If one of these functions is called to initialize a dynamic object that is definitely already initialized by an earlier call, a warning will be issued.
If you have created a custom library model for some function f() in terms of one of these existing models, calls to f() will also be capable of triggering Double Initialization warnings.
English (en)
#include <windows.h>
void double_init(void){
CRITICAL_SECTION cs;
/* ... */
InitializeCriticalSection(&cs);
DeleteCriticalSection(&cs);
InitializeCriticalSection(&cs); /* ok because of intervening DeleteCriticalSection() */
InitializeCriticalSection(&cs); /* warning issued here */
DeleteCriticalSection(&cs);
}
