I have tried to patch octave 3.6.2 but it fails altough differently. I'm not 
completely sure if this is correct.

Here is how I proceeded:
 - I downloaded and uncompressed octave-3.6.2
 - I have copied the modification from savannah and created a patch file in 
octave-3.6.2 directory (see the attached patch file)
 - I have patched the sources with the command: patch -p1 < jordi.patch (the 
modified file is attached; I use p1 because the diff refers to 
a/liboctave/spare-dmsolve.cc)
 - I run configure then make and then make install (I haven't run tests)

When I run test_inpaintZ it stops on the first test (the one with the small 
matrices). The output message and the core dump are attached.

Is that a problem?
