[Bug 1846785] Re: Crashes instantly on launch with Pentium J5005 Processor

[Robie Basak]

Hello milvi, or anyone else affected,

Accepted djvulibre into bionic-proposed. The package will build now and
be available at
https://launchpad.net/ubuntu/+source/djvulibre/3.5.27.1-8ubuntu0.2 in a
few hours, and then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed.  Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, what testing has been
performed on the package and change the tag from verification-needed-
bionic to verification-done-bionic. If it does not fix the bug for you,
please add a comment stating that, and change the tag to verification-
failed-bionic. In either case, without details of your testing we will
not be able to proceed.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance for helping!

N.B. The updated package will be released to -updates after the bug(s)
fixed by this package have been verified and the package has been in

Title:
  Crashes instantly on launch with Pentium J5005 Processor

Status in djview4 package in Ubuntu:
  Invalid
Status in djvulibre package in Ubuntu:
  Fix Committed
Status in evince package in Ubuntu:
  Invalid
Status in djvulibre source package in Bionic:
  Fix Committed

Bug description:
  * Impact
  djvulibre segfaults on older i386 CPU

  * Test case
  try to open a djvu file in evince on an atom based machine

  * Regression potential
  check that djvu files are open fine on newer machines

  ---------------------------------

  [PROBLEM] Djvulibre version 3.5.27.1-8/bionic crashes immediately on intel Atom based processors. (I got a J5005 pentium ).
  Doesn't crash on a  Intel® Core™ i7-7567U.

  Due to this bug https://sourceforge.net/p/djvu/bugs/293/ ,

  and fixed in commit 8407dd, on the 7th of October 2018.

  From git tags, it is included in 3.5.27.1-11 (probably version xxx
  -10, though I cannot see this tag in git history)

  I notice that no dependency change affects any of the versions to the
  build process up to Disco (3.5.27.1-10)

  For intel J5005 (or N5000 on other popular machines ) this bug renders
  the package useless.

  Indeed, it crashes immediately at application startup. Note that this
  affects rdependencies such as evince, djview4.

  I suggest upgrading the version available for Bionic LTS as part of
  the development hardware stack long term support to 3.5.27.1-11.

  Yours sincerly,

  Milvi
