--- Comment #2 from Dominique d'Humieres <dominiq at lps dot ens.fr> ---
The code gives the expected output up to r167173 (2010-11-26), an ICE from
r167380 (2010-12-02) up to r184438 (2012-02-21), and a segmentation fault from
r184852 (2012-03-03) up to trunk (4.10.0, r211378).

The first change may be due to r167220 (pr35810). The second one may be due to
r184651 (pr52386). Both are wild guesses.
