thanks for the giveback, Aurelien.  

weirdly, it seems to have the same problem the second time too.

Back in version 2.1.18-6, we've got no problem on s390x:

but since the upgrade to 2.1.19-3 in experimental, we're seeing the the
segfault on s390x.

I'm not even sure how to interpret the error message: is it saying that
make itself Segfaulted, or that gpgscm segfaulted?

I've connected to zelenka to try to reproduce the problem directly on
s390x but i haven't been able to get there yet.

Any pointers or things i should be aware of for s390x (i'm not used to
this architecture) would be welcome.
