[Qgis-developer] QGIS master crashes on zoom in - zoom out

[Pedro Venâncio]

Hi,

I've compiled and installed yesterday QGIS 2.3 master, on Xubuntu 12.04, but 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. I've tried with the option to render with all processor cores active / deactivated, but it happens exactly the same. I've also uninstalled the CADInput plugin, because I read somewhere that it could give problems, but not resolved.


On the console::

$ qgis
Warning: loading of qt translation failed [/usr/share/qt4/translations/qt_en_US]
Warning: QGraphicsScene::addItem: item has already been added to this scene
no need
false; DefaultProxy; ; ; ; *********;

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

In the first attempt I was using the ubuntugis-stable repository, with gdal 1.9.x. However, I updated all packages with ubuntugis-unstable, and went back to compile, but the same thing happens.

In a last attempt, I tried the nightly builds, also without success.

I've uninstalled everything that was associated with qgis, grass, gdal; erased folders .qgis2 and .config/QGIS, but still crashes...

Error reports always refer to something related to QgsMapRenderer: SIGSEGV in QgsMapRenderer::extent() / QgsMapRenderer::updateScale() / QgsMapRenderer::adjustExtentToSize():

Does anyone have any idea about what may be the cause?


Thank you very much!
