Bug#1022793: libcache-memcached-fast-perl: autopkgtest regression: missing symbols

[Paul Gevers]

Source: libcache-memcached-fast-perl
Version: 0.28-1
Severity: serious
User: debian-ci at lists.debian.org
Usertags: regression
Control: block 1019353 by -1

Dear maintainer(s),

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

                              pass            fail
libcache-memcached-fast-perl from testing    0.28-1
versioned deps [0]           from testing    from unstable
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]. On 
top of that it is blocking the perl transition. Can you please 
investigate the situation and fix it?

[0] You can see what packages were added from the second line of the log 
file quoted below. The migration software adds source package from 
unstable to the list if they are needed to install packages from 
libcache-memcached-fast-perl/0.28-1. I.e. due to versioned dependencies 
or breaks/conflicts.
