It seems to be an issue in symbols; the shlibs get set to
libapt-pkg6.0t64 >= 2.7.11
but the symbol is not present in the outdated container (2.9.4
is what my debian:unstable OCI comes with). Upgrading libapt-pkg6.0t64
to 2.9.14 fixes the issue.
But noticably, we can check our symbols file for apt:
$ grep "_M_replace" debian/libapt-pkg6.0t64.symbols
It's empty, so the dependency should have been generated against
the latest version if anything.
Or rather the problem here is that we are linking this in the
first place, inline functions should be resolved locally, they
are hidden in APT.
I wonder if toolchain people/doko has a clue, because I don't.
The way we built APT is:
-fvisibility=hidden -fvisibility-inlines-hidden
and a linker script:
$ cat obj-x86_64-linux-gnu/apt-pkg/apt-pkg.versionscript
APTPKG_6.0 {global: *; };
to tag all our symbols.
