            Bug ID: 27267
           Summary: Assertion comparing ABIs on rawhide
           Product: libabigail
           Version: unspecified
            Status: UNCONFIRMED
          Severity: normal

  Target Milestone: ---

libabigail-1.8-2.fc33 on x86_64

totem-pl-parser's upstream CI pipeline uses abidiff to make sure that there
aren't unwanted ABI changes between versions.

This currently fails, as the rawhide toolchain seems to have moved to a new
version of DWARF which libabigail doesn't handle.

The error:
abidiff: abg-dwarf-reader.cc:9364: bool
abigail::dwarf_reader::compare_dies_string_attribute_value(const Dwarf_Die*,
const Dwarf_Die*, unsigned int, bool&): Assertion `__abg_cond__' failed.
ABI comparison failed: Command '['abidiff', '--headers-dir1',

died with <Signals.SIGABRT: 6>.

The repository for the library in question, although I don't think it's
necessarily a problem with just this library:
https://gitlab.gnome.org/GNOME/totem-pl-parser/

The CI pipeline:
https://gitlab.gnome.org/GNOME/totem-pl-parser/-/blob/master/.gitlab-ci.yml
if you want to reproduce the problem locally in a container.
