--- Comment #3 from dodji at redhat dot com ---
Hello,

I think the behaviour you are seeing is due to this commit that happened in the
2.1 version, indeed:

https://sourceware.org/git/?p=libabigail.git;a=commit;h=861e4670b611b2f95d69f68bb1edaa15ab5f3aa5.

Long story short, that commit introduced a (minor) incompatibility in the abi
dumps due to a fix in the handling of cloned functions.  Cloned functions is
how some compilers (like GCC) handle the implementation of the different kinds
of destructor functions.  With that fix, libabigail better represents all
cloned functions in its IR. That is why you are seeing more destructors in the
ABI dump.

I bumped the version number of ABIXML to say that users, like yourself, who
rely on abi dumps need to re-generate those dumps with the new version of
libabigail if they want to perform comparisons of the dumps, as opposed to
comparing the binaries directly.

So, long story even shorter, I think the solution would be to regenerate the
dumps with the 2.1 version.  I try to avoid those abixml version bumps, but
sometimes they are necessary, sadly.

Sorry for the inconvenience.
