Hello Serge,
the pythran 0.7.1 now works fine on two of the OpenSuse13.2 machines I use(
a 4 cores and a 2x6 cores). I do not have the segfault anymore, and all the
tests ran successfully.
I was able to run pythran on the small functions of the MANUAL.rst file (
dprod, matrix_multiply, arc_distance ), and I could see with arc_distance
that the performance gain scales pretty well with the number of cores when
using OpenMP, giving an overall gain which can be very interesting.
It seems that some directories are missing in the 0.7.1 tgz file available

Hi Marc and thanks for the good news! Do not hesistate to share your
parallel code snippet so that we can put them on our validation section.

on https://pypi.python.org/pypi/pythran but can be found on github, in
particular the extensions and pythran/tests directories.
After the addition of those two directories, I could test successfully the
%%pythran magic function and do the benchmarks. However I did not understand
the outputs of the latter ...

That's +:- normal for the tests, but the ipython magic should go into
the distribution, you got a point!

I will do more tests later, but this minor revision solved the problems I
had. Thanks !
