I replaced the split implementation in src/ros2/rosidl_typesupport/rosidl_typesupport_c/src/type_support_dispatch.cpp It then crashed for me in very similar code found in src/ros2/rmw_implementation/rmw_implementation/src/functions.cpp After that everything was working for me. It appears to be a bug in the aarch64's libstdc++.6.0.24 -- at least that's the version that I have on my ARM64 machines; it came with GCC 7.2. I was unable to make a simple program that reproduced the problem.
