OK - I was able to reproduce this with

touch src/ros2/rosidl_typesupport_fastrtps/COLCON_IGNORE
colcon build --packages-up-to rosidl_typesupport_cpp --packages-ignore fastcdr foonathan_memory_vendor rosbag2_converter_default_plugins --packages-ignore-regex .*connext.* .*fastrtps.*  
colcon test --packages-select rosidl_typesupport_cpp
