【问题描述】：
一：测试代码:
dhstmt hstmt;
rt = dpi_alloc_stmt(m_hcon, &hstmt);
printf("DEBUG: 00000000000000\n");
char pTest = "DELETE FROM user_info WHERE open_id = ? AND app_id = ?;";
rt = dpi_unbind_params(hstmt);
rt = dpi_prepare(hstmt, (sdbyte)pTest);
printf("DEBUG: 11111111111111\n");
问题: 该代码在CentOS Linux release 7.6.1810 (Core) 上能正常执行。但是在openEuler release 20.03 (LTS-SP2)上会卡在dpi_prepare调用里面，具体堆栈信息为:
