Some failed tests in Octave 3.3.53

[José Luis García Pallero]

Hello,
I'm trying to install the testing version of Octave (3.3.53) in order
to use the package octcdf from octave-forge. I'm working in a centrino
laptop (pentium-m 'banias' 1.3 GHz) running Debian GNU/Linux unstable.
The compilation proccess runs OK, but I've found problems in make
check step. The problems are:

1. Tests failed in time.cc (FAIL 2). Apparently the function 'datestr'
has problems. The log file says:

>>>>> processing /home/topo/Desktop/octave-3.3.53/src/DLD-FUNCTIONS/time.cc
  ***** assert (datestr (datenum (1901, 1, 1), 0), "01-Jan-1901 00:00:00")
!!!!! test failed
assert (datestr (datenum (1901, 1, 1), 0),"01-Jan-1901 00:00:00") expected
01-Jan-1901 00:00:00
but got
01-Jan-1970 00:59:59
  ***** assert (datestr (datenum (1795, 1, 1), 0), "01-Jan-1795 00:00:00")
!!!!! test failed
assert (datestr (datenum (1795, 1, 1), 0),"01-Jan-1795 00:00:00") expected
01-Jan-1795 00:00:00
but got
01-Jan-1970 00:59:59

2. Test failed in chol.cc (FAIL 1). The log file says:

3. The make check process stops (segmentation fault) when testing
imread.m. If I run ./run-octave and try test imread I obtain a bit
more information:

warning: your version of GraphicsMagick limits images to 8 bits per pixel
ocal/bin: magick/pixel_cache.c:2765: ModifyCache: Assertion
`image->cache != (Cache) ((void *)0)' failed.
panic: Aborted -- stopping myself...

*****************************************************************************************

Are these fails known or could be bugs? About imread, should I link
octave against imagemagick instead graphicsmagic? My versions of
graphicsmagick is the one provided in the debian unstable
repositories, 1.3.12, that is, the latest satble.

Other thing. When I start with ./run-octave a warning related with my
.octaverc appears:

warning: /home/topo/.octaverc: possible Matlab-style short-circuit
operator at line 117, column 30

In line 117 of my octaverc says

if strcmp(PAGER(),'less')&isempty(getenv('LESS'))
        PAGER_FLAGS(['-e -X -P"-- less ?pB(%pB\\%):--. (f)orward, (b)ack, ',...
                     '(q)uit$"']);
end

Is '&' not more the 'and' operator in octave? With current 3.2.4
varsion no warning appears.

Thanks
