Bug#1055637: libabigail-2.4: assert violation while setting translation unit for unique types

[Paolo Pisati <paolo.pisati@canonical.com>]

Source: libabigail
Version: 2.4-1
Severity: normal

Dear Maintainer,
while building the zfs-dkms package in Ubuntu/noble, in the checkabi target, abidiff core dumps:

https://launchpadlibrarian.net/696568269/buildlog_ubuntu-noble-amd64.zfs-linux_2.2.0-0ubuntu2_BUILDING.txt.gz

abigail-2.3 was fine, and it started crashing after we moved to abigail-2.4.
I was able to reproduce the issue locally with abigail src from git:

$ abidiff --no-unreferenced-symbols --headers-dir1 include --suppressions
./lib/libnvpair/libnvpair.suppr ./lib/libnvpair/libnvpair.abi .libs/libnvpair.so
abidiff: ../../src/abg-ir.cc:8004: virtual abigail::ir::decl_base_sptr
abigail::ir::scope_decl::add_member_decl(const abigail::ir::decl_base_sptr&):
Assertion `__abg_cond__' failed.
Aborted (core dumped)

and i bisected it down to this commit:

commit d00a2cc2da9b33be5a6e5376cbee4591c042d3a3 (break5)

    Bug 30466 - harfbuzz fails self-check on f38

Sent the report upstream, and got a fix:

https://sourceware.org/bugzilla/show_bug.cgi?id=31045

Tested the fix against zfs-dkms, it built successfully this time.

Can you apply it and cut a new release?
