YAML errors in map_server not caught

[celynw]

When running rosrun map_server map_server map.yaml or equivalent, any errors cause it to close without producing any output. For instance, setting the resolution as a string. I see in the code (map_server/src/main.cpp) it is supposed to produce a ROS_ERROR if the resolution could not be loaded, but this is never printed.

        try {
          doc["resolution"] >> res;
        } catch (YAML::InvalidScalar &) {
          ROS_ERROR("The map does not contain a resolution tag or it is invalid.");
          exit(-1);
        }

In my usage I never get any of these error messages.

I can't find and specifically catch what is being thrown, but catching std::exception::what() does work:

yaml-cpp: error at line 0, column 0: bad conversion

any update?

Setting,

resolution: "0.050000"

within the .yaml

Allows the current method to parse the resolution, is this acceptable?
