Interesting. Since nobody else sees those failures, I guess you'll
need to do some investigation what's wrong. Some of the errors
resemble problems fixed long ago - are you sure you didn't mix up some
sources?
If not, my very wild guess is that maybe your g++ somehow manages to
miscompile Octave. 4.2.1 is somewhat old; maybe there were some bugs?

Try isolating a single piece of code that does not work, for instance
a(1).x.x = 1; a(2).x.x = 2;
a

put it in a script, then try running with ./run-octave -valgrind and
check for invalid memory accesses and the like.
if it does not help, you can try to debug Octave (./run-octave -g).
