MFC CString inside struct: wrong printf-string not detected

[Sebastian Weiser]

cppcheck 1.90

In this little code, the format string does not match the parameter type. In the first call for CString::Format, this is detected as warning (invalidPrintfArgType_sint), but in the 2nd example inside a struct it is not detected.

typedef struct {
    CString st;
} my_struct_t;

void my_func(void) {
    CString my_string;
    double d = 3.1415;
    my_string.Format("%d", d);

    my_struct_t my_struct;
    my_struct.st.Format("%d", d);
}
