I have quite a large ros repo and everything was working fine for a very long time. For some reason running it after Christmas I started seeing the following:

terminate called after throwing an instance of 'std::bad_alloc' what(): std::bad_alloc [kinematic_simulation-5] process has died [pid 42457, exit code -6, cmd /home/jj/ws/phd_ws/ws/devel/lib/perceptive_mpc/as_mpc_simulation_node /joint_states:=/as_control/joint_states __name:=kinematic_simulation __log:=/home/jj/.ros/log/59272bc6-6995-11ec-9acb-dc8b2894491d/kinematic_simulation-5.log]. log file: /home/jj/.ros/log/59272bc6-6995-11ec-9acb-dc8b2894491d/kinematic_simulation-5*.log

I have isolated the error to the following line:

std::string packagePath = ros::package::getPath("perceptive_mpc");

I'm using melodic, docker. the perceptive_mpc package is built and sourced. The line itself is inside the package so its definitely seen. roslib is inside dependencies. I just have no clue at all. Only seen one issue similar online : https://answers.ros.org/question/2963...

Oh and most interesting of all: if I put an absolute path myself instead of using ros:package:getPath -> everything runs fine.

Absolutely any help or advice appreciated!

If anyone encounters this -> Its likely todo with docker setup. In my case it was related to mounting /usr/share. Once I stopped mounting this issue is resolved.
