            Bug ID: 26941
           Summary: abidiff assert in build_or_get_type_decl when
                    comparing a library to itself
           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: ---

With commit 2c0dd017 from dodji/PR26769 I get 

This is probably somewhat related to 26769 but it appears different.
First create an abixml file with abidw then run abidiff on it against the same
library. 

/home/ben/Scratch/Work/test/libabigail-x86_64/bin/abidiff
libabigail.so.0.0.0.abixml /lib64/libabigail.so.0.0.0
[Thread debugging using libthread_db enabled]
Using host libthread_db library "/lib64/libthread_db.so.1".

--- Comment #1 from dodji at redhat dot com ---
This now works for me, with the current master which tip commit is:

18b0693c abipkgdiff: minor cleanups

Note that doing this test is now part of the set of regression tests in
libabigail. It's executed by typing "make check-self-compare".

That test above is not run by default when doing "make check" because it takes
a lot of time and memory (1.6GB and more than 5 minutes on my Rawhide box), but
I run it regularly now.

Thanks for reporting this problem.

--- Comment #2 from Ben Woodard <woodard at redhat dot com> ---
I'm still reproducing this problem in 105 different cases with the libabigail
trunk up through commit 2417efb2

I guess that we assumed that all of these would have the same proximate cause
when in fact they have different causes. 

attached is the full list of files and the RPMs that they come from which still
exhibit this problem.

--- Comment #4 from Ben Woodard <woodard at redhat dot com> ---
Just to illuminate how I test this:

I have debuginfod running and have downloaded all the debuginfo packages for
fedora33. My configuration file is included. The basic idea is that I have a
directory called /data/debug which I added to the default directories that I
tell debuginfod to look into. To keep this up to date I also have a script
called 
freshen-debuginfo.sh which does a reposync of the directories to keep them up
to date. I generally run this before a test run.

I have also downloaded flux-core https://github.com/flux-framework/flux-core
and built that in my environment. I setup my path to my installation of flux
and a current build of libabigail and then run "flux start". I will include
these in the reproducer package as well. But you will need to adjust your paths
as well.

flux start launches a nested shell from which I can run many flux jobs. I have
a script that launches all of those jobs called "flux-abidw.sh". Running that
launches all the jobs and queues them up to be run sequentially as processors
are available.

You can see how many jobs failed by simply running "flux jobs -f failed". On my
system a 6 core i7-8700 running at 3.2GHz it takes about an hour for all the
jobs to complete. However, all but a couple of them are done within about 10
min.

To get the backtraces I have a bunch of other scripts which gather the
backtraces for me. To kick off gathering the backtraces there is a script which
is ./flux-gen-bts-abidw.sh which uses the other scripts ./flux-pull-fails-2.sh
gather-bt-abidw.sh to do the work. What you are left with is a list of files
ending in .bt

Then I pick one of them and look at the line causing the failure and then see
how often it is amongst the backtraces. In this case I looked at 
$ cat libTKBool.so.7.4.0.bt
$ grep -l abg-reader.cc:1287 *.bt | wc -l
105

Then I ran a another program called "all-with.sh" which generated the list I
attached to the commebnt 3.

figured out why dodji and my tests were different.
