I'm down to 56 failures rather than > over 300. 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 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. > However the majority of the remaining problems still seem to hit this pro= blem > just in a different way. 51/56 of the remaining failures look like > this: 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. --=20 Dodji
