Click a shape in a shapefile, QGIS crashes

[acarr@…]

Computer: Fedora Core 5, 64bit QGIS from svn, May 12ish proj and GEOS from repository, GDAL locally compiled, all 64 bit. QT4 from source Compilation of QGIS using GCC 3.x, but some libraries used GCC4 (the default). Steps: 1) Load QGIS 2) Add Vector Layer (choose a shapefile - doesn't seem to matter which, although I was only using polygons...), layer shows on screen. 3) Choose the identify tool, Click on a shape. 4) QGIS crashes:

[mhugent]

My feeling is that this is a 64-bit problem in QgsGeometry::geosGeometry()

[timlinux]

I have had the same problem before on 32 bit platform. I believe its an issue with GEOS. Which exact version of GEOS was QGIS compiled against?

[acarr@…]

RPM version. rpm -q returns: geos-2.2.1-4.fc5

Obviously, I have the devel package, too, same version.

Could it be derived from a compiler mismatch? I had to use the gcc-compat compiler for QGIS, because the main FC5 compiler failed.

I believe there is a patch floating around. I will retest with the GCC 4 compiler and the current libraries.

<<Time Passes While I dl and test the current version (build 5701) >>

It seems to be working now, although I'm not sure on the details of why. The two possibilities which present themselves are:

1) Compiler issues between the RPM library (GCC 4.1) and QGiS (GCC 3.x). I can now compile in GCC 4.1, so I have, and it works.

2) Some change within QGIS which has corrected the problem by itself.

Thanks for looking into it.

Angus Carr.
