            Bug ID: 29911
           Summary: assert at abipkgdiff.cc:1651 when doing a self compare
                    librdmacm-utils
           Product: libabigail
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: default
          Assignee: dodji at redhat dot com
          Reporter: woodard at redhat dot com
                CC: libabigail at sourceware dot org
  Target Milestone: ---

This is with the latest libabigail trunk as of 1f51b9e8

$  fedabipkgdiff --self-compare -a --from fc37 librdmacm-utils
Comparing the ABI of binaries between librdmacm-utils-1.1.0-6.fc27.aarch64.rpm
and librdmacm-utils-1.1.0-6.fc27.aarch64.rpm:

abipkgdiff: ../../../libabigail/tools/abipkgdiff.cc:1651:
abigail::tools_utils::abidiff_status compare_to_self(const elf_file&, const
std::string&, const options&, abigail::ir::environment&,
abigail::comparison::corpus_diff_sptr&,
abigail::comparison::diff_context_sptr&, abigail::fe_iface::status*): Assertion
`__abg_cond__' failed.
...

As far as I can tell this is unique to 2.2 and it affects the following
packages (so far):

librdmacm-utils
llvm12-libs
netcdf-fortran-openmpi
nss-softokn-freebl
socket_wrapper
