It seems that the default branch has the old patch I submitted 
(http://www.cae.wisc.edu/pipermail/bug-octave/2008-January/004837.html) to 
fix this bug, while the release-3-0-x has no patch applied at all.
So, the default branch is not optimal and the release-3-0-x is buggy.
In both cases, the optimal/fixed code snippet should look like the 
one I sent in this thread (dexpm.cc and Cexpm.cc).
Thanks for your effort to fix this bug,

Marco
