I built libgcrypt 1.9.0 with this patch (took it from git.gnupg.org) and
tried to run

$ gpg -s --clearsign -b PKGBUILD

but it ended with the same error for both distribution package and locally
rebuilt one.

Is there a way to debug this? I experimented with running gpg-agent under gdb
and strace but, obviously due to security reasons, couldn't get it to work.
