Original Redmine Issue: 10164
Affected QGIS version: master

Assignee: Martin Dobias

Hi,

After a set of tests [0], I believe there is a problem with QGIS master in Precise 32bits.

It is continually crashing with a segmentation fault (core dumped). I just load a layer (raster / shape / postgis) and do some zoom in / zoom out.

$ qgis
Warning: loading of qt translation failed [/usr/share/qt4/translations/qt_en_US]

Segmentation fault (core dumped)

The faster I zoom in / zoom out, more "breaking!" appears, until the Segmentation fault... See here:

https://dl.dropboxusercontent.com/u/5772257/qgis/crash.ogv
https://dl.dropboxusercontent.com/u/5772257/qgis/crash_nightly.ogv

I've been looking at the tests during compilation, and the segmentation fault appears in qgis_zoomtest:

      Start 43: qgis_shapebursttest
43/92 Test #10102: qgis_shapebursttest ..................***Failed    2.12 sec
      Start 44: qgis_zoomtest

      Start 45: qgis_projectionissues
45/92 Test #10104: qgis_projectionissues ................   Passed   28.29 sec

Looking at the results of the last few weeks in CDash QGIS, this test failed in all builds on Ubuntu 12.04 32bit (and apparently also in Debian Jessie 32bits and Debian Unstable 32bits):

Pedro, are you able to compile QGIS in debug mode and run QGIS in debugger, so that we can get the backtrace? That would help a lot!

Hi Martin,

I tried now with today's nightly build and still crashing, as in http://dash.orfeo-toolbox.org/testSummary.php?project=8&name=qgis_zoomtest&date=2014-06-03

How can I compile and run QGIS in debug mode? Are there instructions somewhere?

Thank you Martin!

Hi again,

I did some tests, compiled with debug mode option, but I dont know if I'm using debug mode correctly. Please see here:

Great, thanks a lot Pedro, this helped to identify where the crash happens (although I'm not entirely sure about the cause).

Great Martin,

If you need I do more tests here, guide me in the process, because it is the first time I am using the debugger.

Thanks!
