[petsc-dev] broken options handling with intel 16.0 compilers on mac OS

[Richard Mills]

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?

Best regards,
Richard
