Closing as requested.

I used gcc 4.8.2. for my compilation. This means that my observed behavior is only a duplicate of bug #47775. There, it was decided to not fix it, but to use a newer gcc version instead.

So please close this bug report.

Is it duplicate of byg#47775?

 What's the gcc version?

This is a 64bit Ubuntu 14.04. (Let me know what linux commands to run to maybe get more detailed information on my machine.)

Is this x86 (32 bit) or x86_64 (64 bit) built?

I have used the code from the "default" code line in the Octave repository, last hg commmit was "4c0f78b3c86f".

When I compile on Ubuntu 14.04 (./configure --disable-docs to avoid compiling problems with osmesa), then I get two failing test:

***** assert (sparse (2i) .^ [3, 4], sparse ([-0-8i, 16]))
!!!!! test failed
ASSERT errors for:  assert (sparse (2i) .^ [3, 4],sparse ([-0 - 8i, 16]))

  Location  |  Observed  |  Expected  |  Reason
    (1)      -1.46958e-15-8i     0-8i       Abs err 2.3054e-15 exceeds tol 0
    (2)      16-3.91887e-15i    16+0i       Abs err 4.3027e-15 exceeds tol 0

>>>>> processing /home/hartmut-nobackup/octave-repo/scripts/specfun/realpow.m
***** assert (realpow (1i,2), -1)
!!!!! test failed
realpow: produced complex result

(And additionally two osmesa related test fail, but that seems to be known and is due to a buggy osmesa version in Ubuntu 14.04.)

Are those two failing test also known, or is there something wrong?
