The first release candidate for Octave version 5.1 is available at
ftp://alpha.gnu.org/gnu/octave/.
I've tried it on my vanilla Linux system (./configure, make) and building
is just fine. Running 'make check' passes with no failed tests.
Please download and experiment on other systems.

I guess that means no errors?
