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=20 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 p= aths as well. flux start launches a nested shell from which I can run many flux jobs. I h= ave a script that launches all of those jobs called "flux-abidw.sh". Running th= at launches all the jobs and queues them up to be run sequentially as processo= rs are available. You can see how many jobs failed by simply running "flux jobs -f failed". O= n 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 w= hich 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 s= ee how often it is amongst the backtraces. In this case I looked at=20 $ 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. --=20 You are receiving this mail because: You are on the CC list for the bug.=
