make: *** [codectest] Error 1

The first line generates the md5sum as expected. There is, however, a
second generation of the file 'a-dv.dv' which produces - of course - a
different md5sum.

---First generation ------------

02c85b9bebb23f147ef598da7bcbf736  ./tests/data/a-dv.dv <------- file
used in the test produces wrong md5 sum

It seems that after the second generation the file 'vsynth.regression'
is not updated.

Ok, this is the info so far, I hope someone can make the dots connected.
