Description

Hi,

As reported on IRC, I experience a segfault at start.
It seems related to lensfun and a particular picture.

The version of lensfun is the latest git one.

Here are the latest commits from "git log":

Only use proper C++ new and delete syntax for object creation in tests and lenstool

Please, find attached:
the backtrace
the .cr2 file
the .cr2.xmp file

Best regards

#1 Updated by Roman Lebedev over 3 years ago

  • Category changed from General to Masks
  • Subject changed from Darktable segfault at start - lensfun related to Darktable segfault at start
  • Assignee set to Aldric Renaudin

Looks like mask issue (did not check if it is reproducible).

#2 Updated by Ulrich Pegelow over 3 years ago

@Jean-Luc: according to the backtrace the crash has been triggered by input file jlc_2566.cr2. Please attach that one. The other input file given earlier does not involve any mask operation nor any lens correction (I agree with Roman that the issue seems to be masks related).

#3 Updated by Jean-Luc Coulon over 3 years ago

Hi Ulrich,

I've made a lots of tests.
I've removed .config/darktable, .cache/darktable, all the .xmp files in the working directory
It was crashing on the first picture if I was opening a signle image or just after populating the thumbnails on the lighttable in the cas I was importing a directory.

After many crashed, the bt are a bit different (it is possible also I made some mistakes: e.g, I've had some file left in /usr/local).

BUT, as lensfun was always in the BT I've. I've got an old package I have on a backup. And thince then I have no problem anymore.

So, I've done a bisect on lensfun (I really need a better computer).

Here is the result:

jean-luc@tangerine] % git bisect bad
9444375fdb5436dd9a4381b92805fd71f69f54fb is the first bad commit

Mark static lfXX::Create() and lfXX:Destroy() functions as deprecated and update documentation accordingly

I suppose this can help

#4 Updated by Torsten Bronger over 3 years ago

A "return" seems to be missing in Lensfun.

#5 Updated by Torsten Bronger over 3 years ago

It is now fixed in Lensfun's git version. Thank you for tracking this down!

#6 Updated by Jean-Luc Coulon over 3 years ago

There is a bit of magic in git-bisect.
BUT I need a better computer because it is a slow repetitive process :)
