Catkin_make seg faults while building messages on ARM
I have a package containing some custom message and service definitions, and when I run catkin_make --pkg mypackage_msgs it will throw a segmentation fault error at a seemingly arbitrary point in the build process.
The output looks something like:

Invoking "make -j4 -l4" failed
but each run changes a little, failing at a different point. I can't find anything wrong with my files.
I'm building on a Raspberry Pi, and the build runs fine when I run it on an x86_64 machine, so I suspect there's some bug in the ARM version of ROS. I've tried doing a catkin_make clean but that doesn't effect the outcome.
How do I fix this error?
I would first check that you're not running out of memory. The Pi has rather limited resources, and compiling ROS (especially msgs) can use quite some memory. I've seen similar errors on systems without swap, fi.
The error
Can't open /usr/local/myrobot/src/ros/build/mypackage_msgs/setup_cached.shlooks unusual as well.@gvdhoorn, I suspect that was the problem, but oddly enough, I just rebooted and re-ran catkin_make with htop running, but I never saw memory usage rise above 10%...and it built without error. I have 1.7GB of swap, which should be plenty, so I'm not sure why low memory would have caused a seg fault.
