I've determined that a certain library I am using is not working properly because CMake is appending -rdynamic to the c++ compiler options for my node's object file. In other words, if I copy and paste the /usr/bin/c++ command generated when using VERBOSE=true catkin_make, and I run that command manually, the node works correctly only if I remove the -rdynamic flag.

How can I edit CMakeLists.txt to remove the -rdynamic flag, and will this cause ROS to break in unexpected ways?

Figured it out:

SET(CMAKE_SHARED_LIBRARY_LINK_CXX_FLAGS "")

If it is really necessary, I'd recommend doing it just for the target that needs it, instead of resetting linking flags for the entire project. CMake supports configuring flags on a per target basis, see target_compile_options.
