I got the same issue with CERTI-3.5.1 on a fresh ubuntu 15.10

It works properly with clang. Changing the gcc version is always
possible, but a boring solution. The issue only happens in the build of
the TestFedTime, so I disabled the build of it locally.

Moreover, the build with g++ success if I change the order of library in
-rdynamic (-rdynamic libRTI.. libFedTime => -rdynamic libFedTime
libRTI), but I do not find the way to force that using cmake.
