I have tried the script with Octave-3.3.50 and the behaviour on my
system is the same.  Thus, the problem seems to be on my side (though
I have no idea were to look at ATM: it is reproduced on two systems
with similar setups).

Well, probably there is a better way :-)  A real script generates data
which is used later. If I save it in a binary file, everything works
(as well as the `testrun' script if one replaces the `diary' commands
with the `save/load' ones). But the script inserts useful comments
while writing data. AFAIK, this is impossible when using `save'.

`eval' is used because names of the newly created files depend on the
names of input files (that are not necessary known beforehand).
