想知道vector<bool>有多坑人吗

void TestVectorBool(){
	vector<bool> vecbool;
	vector<char> vecchar;
	const size_t vecsize = 0x03200000;
	for(size_t i = 0; i < vecsize; i++){
		vecbool.push_back(true);
		vecchar.push_back(1);
	}
	DWORD start = timeGetTime();
	size_t count = 0;
	for(size_t i = 0; i < vecsize; i++){
		if(vecbool[i])
			count += vecbool[i];
	}
	printf("count=%u, %ums\n",count, timeGetTime() - start);

	count = 0;
	start = timeGetTime();
	for(size_t i = 0; i < vecsize; i++){
		if(vecchar[i])
			count += vecchar[i];
	}
	printf("count=%d, %ums\n", count, timeGetTime() - start);
	return;
}
