Details:

I just checked:

1. Current dev system (31 Oct) fails.
2. System built on 26 Oct passes.

The file median.m has not been changed between these
2 systems.

Code that fails (from the median.m tests) is:

rand ("seed", 2);
a = rand (2,3,4,5);
b = rand (3,4,6,5);
x = sort (a, 4);
y = sort (b, 3);
assert (median (b, 3), (y(:, :, 3, :) + y(:, :, 4, :))/2);

error: ASSERT errors for:  assert (median (b, 3),(y (:, :, 3, :) + y (:, :, 4,
:)) / 2)

  Location  |  Observed  |  Expected  |  Reason
 (3,1,1,2)   -6.060400129782798e+78         0.6608      Abs err 6.0604e+78
exceeds tol 0
 (3,2,1,4)   0.3134371936321259        0.8        Abs err 0.48657 exceeds tol
0

This was run from the command line using the 2 dev versions.
The Oct 26 version passes.

The same error
is written to fntests.log on current dev system.
