[Pkg-octave-devel] Unit test bug in octave-signal

[Rafael Laboissière <rafael@debian.org>]

Version 1.3.2-3 of the octave-signal, uploaded yesterday to unstable, 
builds correctly on i386.  However, in order to achieve that, the first 
unit test of function fir2 had to be bypassed [*]:

#######################################
***** xtest
 f = [0 0.6 0.6 1]; m = [1 1 0 0];
 b9  = fir2 (30, f, m, 9);
 b16 = fir2 (30, f, m, 16);
 b17 = fir2 (30, f, m, 17);
 b32 = fir2 (30, f, m, 32);
 assert ( isequal (b9,  b16))
 assert ( isequal (b17, b32))
 assert (~isequal (b16, b17))
 !!!!! known failure
 assert (isequal (b9, b16)) failed
#######################################

This is a highly strange bug that I cannot replicate on my i386 chroot 
(running on an amd64 system).  If someone has access to a native i386 
system and could track down the problem, I would be grateful.
