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=3DReleas=
e/43/consoleFull
https://allendale.engr.mun.ca/jenkins/job/LLVM-cadets/BUILD_TYPE=3DDebug/=
43/consoleFull

With BUILD_SHARED_LIBS=3DOFF, both builds succeed.
