ros::master::check() block after several calls

edit

Hi,

I have a C++ programm where I want to check if the master is connected before starting the nodeHandle.

I first call ros::init() with the right arguments and then call : while(!ros::master::check()) to wait indefinitely until the master is connected.

Unfortunately my program freeze after only a few calls to the check() function. I also tried to wait a few seconds between each call but that didn't change anything.

Is there a way to fix this ? or to wait for the master to connect with a better method ?
