Oh? Other packages in this situation have mostly been failing to link,
because the name-mangling of names that mention std::string changed. I'm
not sure why that wouldn't have happened here if the ABI did change.

You mean you've been building cadabra with g++ 5 against the old
modglue?  Or against the already-binNMUed modglue?

Cheers,

OK, now I see what my error was: I hadn't noticed that modglue had
already been binNMU'd with g++-5, for the libsigc++-2.0-0v5 transition
(and therefore it has the g++-5-flavoured ABI already).

Thanks,
S
