Hello Robie,

testing djvulibre-bin :
testing command : djvups, djview4 
hardware : atom based processor (Pentium J5005)

- 3.5.27.1-8ubuntu0.1

$ Segfault (core dumped)
(as expected)

then with version,

- 3.5.27.1-8ubuntu0.2

It works ! It now returns and produces a valid postscript file.


djview4 (version 4.10.6-3) works only when the patch is applied 
(3.5.27.1-8ubuntu0.1 -> 3.5.27.1-8ubuntu0.2).
To check this, I ran djview4 before and after upgrade.

Regression on an Intel® Core™ i7-7567U doesn't trigger any failure. 
- djvups, djview4 run like a charm as before.


Thanks a bunch,

There is a community out there reading old research material, digitized
papers, and books, the likes of which are often found in DJVU format.
You have opened access again to half my disk's content !

Hello milvi, or anyone else affected,

Accepted djvulibre into bionic-proposed. The package will build now and

few hours, and then in the -proposed repository.

Please help us by testing this new package.  See

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

** Description changed:

+ * 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
