Hi again, I actually deleted the build directory before I built again with Debug.
Now I freshly cloned the code, created build directory git clone -b release-2_12 --single-branch https://github.com/qgis/QGIS.git QGIS_2_12 cd QGIS_2_12 mkdir qgis-2.12 cd qgis-2.12/ ccmake .. #There in the CMAKE_BUILD_TYPE line I entered "Debug" make gdb ./output/bin/qgis Result is the same as before: "No stack" Any ideas?

Maybe you have to "make clean" before running "make" again? It seems that there are no debug symbols available yet. And once they are available, it seems that there's still an issue with X of which I am not sure if it brings the application to its knees even before it arrives at the point where the crash we are interested in is.
