有効/無効設定 このワーニングクラスのチェックはデフォルトで無効になっており、プロジェクトには非正規の C向けAST が必要になります。有効にするにはプロジェクト設定ファイル （configuration file） に以下の WARNING_FILTER ルールと RETAIN_UNNORMALIZED_C_AST 設定を追加してください。 
RETAIN_UNNORMALIZED_C_AST = Yes
WARNING_FILTER += allow class="Inappropriate Storage Duration"
注：非正規化された AST を継続して使用した場合、使用ディスク容量が増加し解析時間が長くなる可能性があります。

例 

#include <threads.h>

_Thread_local mtx_t m_tl; /* 'Inappropriate Storage Duration' warning issued here */

_Thread_local int i_tl;            /* ok: type is not thrd_t, mtx_t, cnd_t, or tss_t */

static mtx_t m_static;             /* ok: duration is not thread or automatic */

void c_thread_isd(void){
    mtx_t m_l;            /* 'Inappropriate Storage Duration warning' issued here */
    static mtx_t m_sl;             /* ok: duration is not thread or automatic */

    /* ... */
