I can't provide that easily because of package upgrades.

However, I got a similar but slightly different crash today:

https://bugzilla.gnome.org/page.cgi?id=traceparser/trace.html_id=238398
https://bugzilla.gnome.org/attachment.cgi?id=368394

In frame 0 of thread 1, what do the following gdb commands say?

  print *pCache
  print *pPage

Thanks,

I see, thanks for the information and investigation.

You can browse the Debian source code here:

https://sources.debian.org/src/sqlite3/3.21.0-1/

You can browse the Debian patches here:

https://sources.debian.org/patches/sqlite3/3.21.0-1/

You can download the Debian source code here (debian.tar has patches):

http://deb.debian.org/debian/pool/main/s/sqlite3/sqlite3_3.21.0-1.dsc
http://deb.debian.org/debian/pool/main/s/sqlite3/sqlite3_3.21.0-1.debian.tar.xz

You can view the build logs for the package here, in the Status column:

Note that the crash was on amd64 and logs are not available for that.

There are no known issues like this with any recent version of SQLite.
Usually these kinds of things end up being heap corruption in the
application.  Nevertheless, we will investigate from the SQLite side,
just in case.

"SQLite 3.21.0-1" is not an official SQLite product.  It must be a
version of SQLite that has been customized by Debian.  Where can we
get a copy of Debian's customized code?

[sqlite] sqlite3 related crash (SIGSEGV) in GNOME tracker-store

[Paul Wise]

Hi all,

I got a couple of random crashes GNOME's tracker-store daemon that
appear to be related to sqlite3. I use 3.21.0-1 from Debian buster.

https://bugzilla.gnome.org/show_bug.cgi?id=791243

The short backtraces are available here:

https://bugzilla.gnome.org/page.cgi?id=traceparser/trace.html_id=238220
https://bugzilla.gnome.org/page.cgi?id=traceparser/trace.html_id=238281

The full backtraces are available here:

https://bugzilla.gnome.org/attachment.cgi?id=365000
https://bugzilla.gnome.org/attachment.cgi?id=365891

Is this a bug in sqlite3 or is it caused by data corruption?

PS: please either CC me in response or post on the GNOME bug.
