Blaise and Satish, I'm a bit slow to pick up on this thread as I was busy traveling, but since I use a Mac and work for Intel, I thought I should see if I could reproduce the problems that Blaise is seeing. I installed the 16.0 compilers and built a simple configuration ('--with-debugging=1 COPTFLAGS="-g -O0" FOPTFLAGS="-g -O0" CXXOPTFLAGS="-g -O0" --with-blas-lapack-dir=/opt/intel/compilers_and_libraries_2016/mac/mkl --with-mpi-dir=/Users/rtmills/packages/mpich-3.1.4-intel') using a very recent revision of 'master' (09b4d96fa5749f82a0af9a914729f77a4ef2b2fd, Sun Sep 20 22:51:31 2015 -0500). When I try running SNES ex5f and passing various command-line options, everything appears to work fine. Any suggestions for digging deeping into this to try to determine the difference between what Blaise and I are seeing?

Hm - I would suggest doing a minimal build build with:

--with-cxx=0 --with-clib-autodetect=0 --with-fortranlib-autodetect=0 LIBS="/opt/intel-16.0/compilers_and_libraries_2016.0.083/mac/compiler/lib/libifcore.a"

And see if that makes a difference. Satish,

It does help. Turning off auto detect leads to a functional build, turning it back on leads to a non-functioning one.

The configure.log without auto detect is here:
