Bug#911090: libapt-pkg5.0: incompatible with apt/stretch

[Andreas Beckmann]

Package: libapt-pkg5.0
Version: 1.7.0
Severity: serious

Hi,

I just did a partial upgrade on a stretch+buster+sid development
system resulting in apt-get erroring out with

apt-get: relocation error: /usr/lib/x86_64-linux-gnu/libapt-private.so.0.0: symbol _ZN3URIcvNSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEEEB5cxx11Ev version APTPKG_5.0 not defined in file libapt-pkg.so.5.0 with link time reference

Looks like some Breaks may be needed ...

probably the relevant package mixture:

ii apt 1.4.8 amd64 commandline package manager
ii dpkg 1.19.2 amd64 Debian package management system
ii libapt-pkg5.0:amd64 1.7.0 amd64 package management runtime library

So, I think this affects more than just apt. gcc 7 broke the ABI
by adding a new mangling

URI::operator std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >()

and only linking to that. It seems that some new gcc version then
got rid of the old one

URI::operator std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >[abi:cxx11]()

and now it's crashing.

And that's a problem for _every_ library with operator string(), not
just apt.
