It's actually octave-gui that is segfaulting.  The cause is that the
executable is bringing in both libstdc++ and libc++, and the reason for
that is likely the addition of USE_GCC=yes to the port Makefile that was
done at the same time as the version upgrade.

I have no idea what happens if USE_GCC=yes is removed from the Makefile.
there may be problems with compiling the source with the combination of
clang and gfortran.  I'll give it a try, though.

Another possibility would be do disable the gui.  Looking at configure,
there is a --disable-gui option that we don't expose as a port option. I
don't know what libraries are needed by the gui, but of all the
libraries in LIB_DEPENDS, libfltk.so, libftgl.so, and libqscintilla2.so
are the ones that are linked to libc++.so.

Unfortunately, "octave --no-gui" doesn't work.  It still tries to run
octave-gui and dies.
