Thanks for testing this Ben!

Before I can move forward on this, I need to get in a new test harness
to regression-test this.  The thing is that this binary has its debug
info stripped out and compressed with dwz, as part of the normal process
that binaries packaged in RPM for Fedora go through.

So I am looking into coming with a new abikpkgdiff --self-check <rpm>
option that would compare each binary in a rpm against its abixml
representation.  I would then add the rpm of libstdc++ to the testsuite
and have a new harness that would run abipkgdiff --self-check on it.

Once I have this, I can proceed with contemplating merging this in.

I see.  I'll look into this right away when I am done with the above.
Hopefully, fixing this will bring the number of issues down
dramatically.

Thanks for looking into this.
