[Debian-med-packaging] Bug#1016742: libcereal: autopkgtest regression: add_subdirectory given source "sandbox" which is not an existing directory

[Paul Gevers]

Source: libcereal
Version: 1.3.2+dfsg-1
Severity: serious
User: debian-ci at lists.debian.org
Usertags: regression

Dear maintainer(s),

With a recent upload of libcereal the autopkgtest of libcereal fails in 
testing when that autopkgtest is run with the binary packages of 
libcereal from unstable. It passes when run with only packages from 
testing. In tabular form:

                        pass            fail
libcereal              from testing    1.3.2+dfsg-1
all others             from testing    from testing

I copied some of the output at the bottom of this report.

Currently this regression is blocking the migration to testing [1]. Can 
you please investigate the situation and fix it?
