QGIS » QGIS Application

I did a "git pull" 4 or 5 minutes ago :-)

Now I'm compiling QGIS with debug to watch more on this error...

Doing gdb, the error is here:

0x00007ffff3dd3438 in QgsClipper::clippedLineWKB (wkb=0x7fff70033ffb "", clipExtent=..., line=...) at /home/manganelll/qgis-git/QGIS/src/core/qgsclipper.cpp:72
72            memcpy( &p1x, wkb, sizeof( double ) ); wkb += sizeOfDoubleX;

The error is "Program received signal SIGSEGV, Segmentation fault."

it works ok on previous qgis releases?

Another machine - 32 bit, Debian Squeeze, QGIS 2.0: all is running fine.

Testing with QGIS last weekly (2014-06-02) on Windows 2003 Server: after loading the layer, QGIS crashes.

I also get many crashes with the following (mostly SpatiaLite-based) project https://drive.google.com/folderview?id=0Bwc-5JFVTnfIZURsbzVHOHVYMjA&usp=sharing

Sometimes - but not always - when opening the project, sometimes when zooming.

confirmed here all the time when zooming. But it happens also if disabling simplification on all layers, so it may be worth a different ticket.

Giovanni / Anita: looks like a different problem. I haven't checked with Anita's data thoroughly yet, but the problem may be related to fix for #9655 (used also if simplification is turned off). Could you please verify it happens just with labeling turned on?

Anita / Giovanni: seems to be the same thing as #10433

Hi Martin it seems at least that the crash is caused by two different actions: in one case is the zoom, in the other is a change of symbology.

Anyway I'm compiling and see if both cases are still true.

Hi Martin, I just compiled the latest code and now by just simply opening/zooming Anita's project I cannot replicate anymore the crash.

On the other hand #10433 is confirmed and it seems caused by labels, see my last comment there.

Yes, now it works! Great! :-)
