Did you have LD_LIBRARY_PATH=/opt/OpenBLAS/lib in the environment when
running `make check` also? Can you see if that makes a difference?

In case you're not sure how to do that, either

  export LD_LIBRARY_PATH=/opt/OpenBLAS/lib
  make check

or

  LD_LIBRARY_PATH=/opt/OpenBLAS/lib make check

Does the test still fail with a segmentation fault?

Ok, you haven't quite configured Octave correctly for large arrays. Are
you sure you need the --enable-64 option? If you really want to build
against a 64-bit-indexed OpenBLAS, then you also need to take care of
SuiteSparse, ARPACK, and QRUPDATE, or build Octave without these
libraries at all. Your configuration picked up some of the system
SuiteSparse libraries, that may be causing this error, and will
definitely cause other errors.

If the above doesn't fix anything for you, can you try building (again)
without --enable-64 and without /opt/OpenBLAS? What is the error in this
case?
