This is probably due to some changes in either Cray C++ or the vendor provided PETSc. Reverting back to CCE 7.3.1 by issuing the following commands solves the problem.
module swap PrgEnv-pgi PrgEnv-cray (Assuming that PrgEnv-pgi is the default environment)
module swap cce cce/7.3.1.101
module swap xt-libsci xt-libsci/10.5.0
module add petsc/3.1.04
