strange overwritten error with

[wjwwood]

For example on my machine, while testing alpha 6:

% two_node_pipeline__rmw_fastrtps_cpp
[rmw|error_handling.c:93] error string being overwritten: not implemented, at /Users/william/ros2_ws/src/eProsima/ROS-RMW-Fast-RTPS-cpp/rmw_fastrtps_cpp/src/functions.cpp:1768

^Csignal_handler(2)

It is because of this nonsense that I had in the fastrtps function to get the graph guard condition:

I'm working on a fix.

Your fix got merged, so we can close this, right?

[wjwwood]

Yup.
