The link error suggests 2 different versions of MPIUI_Thread are used.
But I can only see a definition in src/util/thread/mpiu_thread.c. src/mpi/comm does not refer to it, and comm_rank.c does not use any
MPIU object. So the error message doesn't make sense to me.
comm_rank's reference to MPIUI_Thread is also present on at least amd64,
and presumably due to some macro that (directly or indirectly) calls MPIU_THREADPRIV_FIELD. However, it's not clear why multithreaded build settings would be in effect for mpiu_thread but not also comm_rank. (It
looks like MPIUI_Thread's thread-locality is conditional on
MPICH_IS_THREADED, which mpichconf.h defines centrally.)
I don't have time to dig deeper, but hope that brief analysis helps.
