我用-fsanitize=address编译代码，得到以下错误：

SUMMARY: AddressSanitizer: new-delete-type-mismatch (/usr/lib/gcc/x86_64-pc-linux-gnu/7.3.0/libasan.so.4+0xe1938) in operator delete(void*, unsigned long)

生成的代码是：

bool Job::process_job(sql::Connection *c) {
    try {
        std::unique_ptr<sql::PreparedStatement> pstmt;
        std::unique_ptr<sql::ResultSet> res;

        pstmt.reset(c->prepareStatement(sql_select1));
        pstmt->setString(1, player_id);
        res.reset(pstmt->executeQuery());
        while (res->next()) {
            // Processing results...
        }

    } catch(sql::SQLException &) {
        return false;
    }

    return true;
}

似乎当unique\u ptr超出范围并删除pstmt时就会发生这种情况。但这是什么？我做错什么了吗？
我使用：
x86_-pc-linux-gnu-7.3.0
mysql-connector-c1.1.6
glibc 2.26-r7标准
最有趣的事实是，在系统上使用相同的编译选项时，相同的代码工作正常，没有问题和内存泄漏：
x86_-pc-linux-gnu-7.3.0
mysql-connector-c1.1.6
glibc 2.23-r4型
