I just hit exactly the same crash trying to run abipkgdiff on old and new versions of the abc package.  This time I used the Fedora 33 version of the package:

libabigail-1.7-2.fc33.x86_64

GDB says:

abipkgdiff: abg-dwarf-reader.cc:14645: void abigail::dwarf_reader::finish_member_function_reading(Dwarf_Die*, const function_decl_sptr&, const class_or_union_sptr&, abigail::dwarf_reader::read_context&): Assertion `__abg_cond__' failed.

Thread 10 "abipkgdiff" received signal SIGABRT, Aborted.

I'm not sure what is relevant.  Let me know if you want me to provide further information.

This message is a reminder that Fedora 33 is nearing its end of life.
Fedora will stop maintaining and issuing updates for Fedora 33 on 2021-11-30.
It is Fedora's policy to close all bug reports from releases that are no longer
maintained. At that time this bug will be closed as EOL if it remains open with a
Fedora 'version' of '33'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora 33 is end of life. If you would still like 
to see this bug fixed and are able to reproduce it against a later version 
of Fedora, you are encouraged  change the 'version' to a later Fedora 
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

Fedora 33 changed to end-of-life (EOL) status on 2021-11-30. Fedora 33 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
bug.

Thank you for reporting this bug and we are sorry it could not be fixed.
