Bug#997884: libgclib breaks cdbfasta autopkgtest: ABI breakage?



Source: libgclib
Control: found -1 libgclib/0.12.7+ds-2
Severity: serious

Control: affects -1 src:cdbfasta

Dear maintainer(s),

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

                       pass            fail
libgclib               from testing    0.12.7+ds-2
cdbfasta               from testing    1.00+git20181005.014498c+dfsg-2
all others             from testing    from testing

I copied some of the output at the bottom of this report. Looking at the
message and the changelog, it seems that symbols were changed, but this
one was apparently used by cdbfasta. I think this points at an ABI
breakage and the SONAME of libgclib must be bumped and a transition must
be followed through. (I could be wrong).

Currently this regression is blocking the migration of libgclib to
testing [1]. Can you please investigate the situation?
