So this is interesting: the build succeeds in Release mode but fails in 
Debug:

https://allendale.engr.mun.ca/jenkins/job/LLVM-cadets/BUILD_TYPE=Release/43/consoleFull
https://allendale.engr.mun.ca/jenkins/job/LLVM-cadets/BUILD_TYPE=Debug/43/consoleFull

With BUILD_SHARED_LIBS=OFF, both builds succeed.
