I get this error when compiling a piece of code which uses bondcpp with clang. Compile command is as follows:

catkin build -DCMAKE_C_COMPILER=/usr/bin/clang -DCMAKE_CXX_COMPILER=/usr/bin/clang++ -DCMAKE_BUILD_TYPE=Release

@VasuAgrawal do you have any further information on this? What version of ROS are you using? What version of bond are you using?
