Hi all,

ABI was broken in controller_manager (part of ros_control) between versions
0.9.3 and 0.9.4, released in Indigo.
Since the sync on April 22nd, any upgrade of ROS binary packages can result
in segfaults in your robot hardware driver (or whatever software component
using controller_manager)

If this affects you, you will need to rebuild your software against
controller_manager 0.9.4.

Cheers,
