The error message at

https://github.com/ros-drivers/camera1394/blob/abc1950a6925628acc7581cabc312741706b6e4c/src/nodes/dev_camera1394.cpp#L197-L200

is longer than 100 chars, and GCC 8.3 started figuring this out and reports a warning about the buffer being too small (the size computed by gcc is 165 chars).
