Hi reproducible team,
I wish I could give you a detailed bug report, but instead you get a
very vague one. Sorry about that.
Since the 24th I am observing that all rebootstrap_*_diffoscope jobs on
jenkins.d.n fail no later than running diffoscope on libc6. Given the
date, we can be pretty sure that the regression was introduced precisely
in version 47.
The actual failure is rather unspecific. diffoscope is killed by timeout
with SIGKILL after running for more than an hour. You can see an example
failure log at
One also sees that it works just fine on libc6-pic for instance.
So I tried to copy one of those packages off the host
profitbricks-build4-amd64.debian.net to run a local diffoscope and
inspect the issue. Instead the very same diffoscope in a very similar
amd64 chroot was done analyzing within just 2 minutes. In reality, I
couldn't reproduce the issue at all, but it still persists on that
What else could I tell? It's using the --text output mode. It's always
run on an amd64 system and always on non-amd64 binary packages.
Recommends are turned off, but binutils-multiarch and vim-common are
I also found looking into munin a bit interesting:
Since precisely the 24th, it started swapping a lot more and there are
large spikes in the resident memory usage. There is a chance that we can
attribute this to diffoscope.
Then I looked through the commits between 46 and 47 and the only thing
that caught my eye was the automatic use detached debug symbols. In my
own tests, I was never able to make that work (according to --debug
output), so maybe the feature works on
Even though I cannot reproduce the issue at hand, I think that the code
adding automatic debug symbols looks fishy to me. It appears to recurse
over /tmp here and that looks very wrong to me. /tmp is small here, but
on the jenkins slave, /tmp is big.
Any further ideas for debugging this?

Binary: diffoscope debbindiff
Architecture: source all
Maintainer: Reproducible builds folks
Changed-By: Jérémy Bobbio <lu...@debian.org>
debbindiff - transitional package
diffoscope - in-depth comparison of files, archives, and directories
diffoscope (49) unstable; urgency=medium
[ Jérémy Bobbio ]
* Don't crash when we can't find the debug file in a matching debug package.
This repairs diffoscope for xserver-xorg and other packages.
* Use libarchive to read metadata from ar archives. The output is more
precise and less dependent on binutils version. The command line `ar` tool
is not used any more so remove it from the required tools.
* Split readelf --debug-dump output when examining ELF files. Based on a
patch by Dhole.
* Keep both .debug_str and .zdebug_str as ElfSection. Thanks to Niels Thykier
for noticing the problem.
* Fix a logic error in _install_debug_symbols. Thanks anthraxx for the report
and the fix.
* Use recursive containers for directory and only look at files with ending
in .deb when looking for Build IDs. Both avoid looking at too many files
when searching for matching debug packages. Thanks Helmut Grohne and Steven
Chamberlain for the reports and tests. (Closes: #813052)
* Add support for ICC profiles. This adds a Recommends on colord in Debian.
* Harmonize spaces and commas in package list.
* Update PPU files test data for FPC 3.0.0.
* Update exepcted javap output for OpenJDK 1.8.
* Stop specializing files from directories earlier than necessary.
[ anthraxx ]
* Adding cd-iccdump package reference for Arch Linux.
[ Mattia Rizzolo ]
* Use HTTPS in Vcs-Git.
[ Holger Levsen ]
* Bump standards version to 3.9.7, no changes needed.
* Use /git/ instead /cgit/ in Vcs-Browser.
