Ok, so the difference to my (in the second run) successful build
inside pbuilder are:

* No rebuild of libsigc++2.0
* Boost 1.55

We (Manuel and me) expect potential issues with Boost 1.58 (as usual
with Boost version bumps). Maybe it's them.

I'll check as soon as I find time for such a rebuild-chain.

I assume you mean libsigc++-2.0. (libsigc++ has been removed from Sid
in 2014: https://bugs.debian.org/735559; reported by Manuel)

Anyway, that will save me at least the xapian-core rebuild. :-)

I don't see any such bug for cppunit, actually I see no cppunit bug at
all: https://bugs.debian.org/cgi-bin/pkgreport.cgi?src=cppunit

Ah, did you mean library transition bugs? Like

I have no hands-on experience with library transitions and I can't
code in C++. So I don't think, I'm a good choice for that.

*nod* My current plan is to upload aptitude once all the reverse
dependencies, I had to rebuild, are BinNMUed or had a fresh,
gcc5-related upload (and are built on all architectures preferably).

(Cc'ing aptitude's FTBFS-with-gcc5 bug #777778 instead of just its
maintainer mailing-list.)
