我在windows10上使用mysql连接器/c++。我发现当我打电话的时候 get_driver_instance 从全局对象的c'tor开始，它只是抛出异常：访问冲突读取位置。
示例代码：

# define CPPCONN_LIB_BUILD // Need to include this as we are linking mysql connector in static library

# include "MySQL\Src\mysql-connector-c++-1.1.5\cppconn\driver.h"

# pragma comment(lib,"MySQL\\Src\\mysql-connector-c++-1.1.5\\BLD\\driver\\Debug\\mysqlcppconn-static.lib")

# pragma comment(lib,"MySQL\\Src\\mysql-5.6.24\\BLD\\libmysql\\Debug\\mysqlclient.lib")

struct someclass
{
    sql::Driver *m_pDriver;

    someclass()
    {
        /* Create a connection */
        m_pDriver= get_driver_instance(); // It crashes here
        cout << "print something";
    }
} someclass_instance;

int main(int argc, char**argv) 
{
    // We don't need to do anything here. The problem occurs in the global class constructor which executes before main as we've defined its global instance.

    return 0;
}

引发的异常类似于：
sample.exe中0x000007f6be17485d处出现未处理的异常：0xc000005:访问冲突读取位置0x00000000008。
崩溃时的堆栈跟踪：

令人惊讶的是，这只发生在调试构建中。然而，这与本问题中提出的情况不同。我已经确定我正在链接调试生成的连接器库。如果我示例化同一个对象 someclass_instance 但在main函数中，它并没有崩溃。这真的很奇怪。我怀疑与crt初始化有关，但不确定是否通过。
注意：我花了好几个小时才弄明白。这是真正的问题。在投票之前，请至少尝试一次代码。
如果有人能发光就好了。
