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="Mismatched Argument Types"
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。

#include <string.h>

void lang_type_mat_incompatible(int *pi,
                                unsigned int *pui,
                                char *pc){
    (void) memcpy(pi, pui, 2); /* 'Mismatched Argument Types' warning issued here
                                * - 'int' and 'unsigned int' are not compatible */
    (void) memcpy(pi, pc, 2);  /* 'Mismatched Argument Types' warning issued here
                                * - 'int' and 'char' are not compatible */
    (void) memcpy(pui, pc, 2); /* 'Mismatched Argument Types' warning issued here
                                * - 'unsigned int' and 'char' are not compatible */
}

void lang_type_mat_qual(int *pi,
                        const int * pci,
                        volatile int * pvi){
    (void) memcpy(pi, pci, 2);            /* differ only in qualifier */
    (void) memcpy(pi, pvi, 2);            /* differ only in qualifier ('Incompatible Parameter' warning issued) */
    (void) memcpy(pvi, pci, 2);           /* differ only in qualifier ('Incompatible Parameter' warning issued) */
