程序报std::bad_alloc异常

C++程序，报std::bad_alloc异常，我知道是内存不够new操作失败导致。现在想知道有没有方法增加程序的内存？按理说这个板子6GB内存足够大了，我的程序用不了多少了内存的，肯定是编译命令还是哪里出错了

是RTSPClient 对象调用enable函数时出了这个std::bad_alloc异常错误

你自己程序有内存泄漏吧？

我只是刚加了自己的代码进去，没调用过，不影响程序。

gdb debug下啊

seetaface6与rockchip的rtsp库有冲突吧？只要加入seetaface库,RTSPClient .enable（）函数必报std::bad_alloc异常错误

我不知道啊，这个rtsp client都是我们另外一个工程师私自写的，没人维护的，这东西都是demo，真正要用，建议你用其他第三方更稳定的库做。。。
