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

2020-06-03 Thread milvi
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 !

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

2019-10-04 Thread milvi
Public bug reported:

[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
