linux下OCI开发Oracle ，OCIServerAttach卡死问题

[wzy9854]

最近在研究linux下OCI接口，写了一个connect函数，结果不能用，每到OCIServerAttach就会卡死，用gdb调试还会报出
siglongjmp 信号错误 不知道是linux环境没配置正确 还是tnsnames.ora有问题
编译也能通过，程序也能跑起来不报错，就是会卡在OCIServerAttach函数，求大神啊！！！！
代码如下，应该不会是代码的问题T.T

请修改操作系统 ulimit -n参数，我这边把ulimit -n改小很容易重现 我认为虽然这个参数是对一个进程限制，但手动启的程序或用system启的进程都属于同一个父进程

为什么结贴，你用哪种方式解决的？
