[Martin Vernhout]

Bug report for Octave 3.0.3 configured for i386-apple-darwin8.9.1

Description:
-----------

when saving large datasets, i found that saving in matlab v7 format failed repeatedly
 with error "error compressing data element"
on my system, it's reproducible 


Repeat-By:
---------

% create large datafile
large=rand(1e6,10);
save -mat7-binary largedata7
% this will invoke error: save: error compressing data element
% test with save -v6 largedata6

Fix:
---

currently i'm using matlab 6 format... but i don't like it ;-)
