这是在双核32位Vista机器上的Visual Studio 2008上.在调试代码中运行正常,但在发布模式下这个炸弹:

void getFromDB(vector<string>& dates) {
    ...
    sql::Resultset res = stmt->executeQuery("SELECT FROM ...");
    while (res->next()) {
       string date = res->getString("date");
       dates.push_back(date);
    }   // <<< crashing here (line 56)
    delete res;
}

MySQL C++连接器在它的ResultSet中有这个方法:

virtual std::string getString(const std::string& columnLabel) const = 0;

由于某些原因,在编译版本中(针对MySQL C++连接器DLL),这会在循环结束时因堆损坏而崩溃:
