We see similar with python updates as well.

--- Comment #2 from dodji at redhat dot com ---
Hello,
I could not reproduce the issue because there is some debuginfo missing from
the tarball you submitted.
For instance, in the libsqlite3 tarball, the debug info that is missing is
{new,old}-image/usr/lib/debug/dwz/components/sqlite.bst/x86_64-unknown-linux-gnu.
It's called an 'alternate debuginfo file'.
That debug info file is referenced by the main debuginfo file
{new,old}-image/usr/lib/debug/usr/lib/x86_64-linux-gnu/libsqlite3.so.0.8.6.debug.
Could you please provide an updated tarball with that alternate debug info file
in?
Thank you for taking time to report this problem and sorry for the
inconvenience.

Frustratingly I've nuked my local build environment for this, but I should be
able to kick off another build this evening. It should also be reasonably
straightforward to extent the CI to include this additional debuginfo within
the tarball.
Is there an easy way to programmatically extract the path to the alternate
debuginfo file? I've tested with `objdump -Wk <binary.debug>` which gets me
something I can run a regex match against, but I'm wondering if there's
something more direct.

No problem, thank you for following up.

So, here is maybe a starting point.
the ".gnu_debugaltlink" section of the main debuginfo file contains the
path to the alternate debuginfo file.
Let's examine the section headers of the of the main debuginfo file and
see if the .gnu_debugaltlink section is in there:
$ readelf -S libsqlite3.so.0.8.6.debug | grep .gnu_debugaltlink
[35] .gnu_debugaltlink PROGBITS 0000000000000000 00201f1c
Right it's in there.
Now, let's read its content, as a string:
$ readelf --string-dump=.gnu_debugaltlink libsqlite3.so.0.8.6.debug
String dump of section '.gnu_debugaltlink':
[ 0] /usr/lib/debug/dwz/components/sqlite.bst/x86_64-unknown-linux-gnu
[ 42] ;?^UW+%^[w^\E^AC^K^:
$
I hope the above is useful.
Thanks again!

Thanks for the pointers!
I've just attached an updated tarball which includes the alternate debug files.
