[Qgis-user] QGIS Segmentation fault

[Blumentrath, Stefan]

Yes I did. Now I also tried

export CMAKE_BUILD_TYPE=Debug

Befor running (earlier I specified Debug in the cmake gui):
ccmake ..
make
gdb ./output/bin/qgis

Cheers
Stefan

Did you make after cmake with buld type Debug and before running? Sorry, I forgot to write that...
