--- Comment #116 from caulier.gil...@gmail.com --- Well the backtrace revelate 2 points : 1/ None of thumbnail storage format or OpenCL introduce the dysfunction. 2/ As Maik said, a wrong overloaded function is called from the thumbnail engine. So i suspect a dysfunction with your compiler, probably a compilation option used when you run make. Please give me the result of "g++ -v" from a console. Here with the g++ 5.5.0 (the base from Mageia6), i never seen this kind of crash from the thumbnail engine. Also, I'm curious to see which options are passed by KF5::ECM component to g++ while compilation. To check this point it's very simple. From a console, go to build directory of thumbnail engine and run : [gilles@localhost threadimageio]$ export VERBOSE=1 [gilles@localhost threadimageio]$ pwd /mnt/devel/GIT/6.x/build/core/libs/threadimageio [gilles@localhost threadimageio]$ make clean cd /mnt/devel/GIT/6.x/build && make -f CMakeFiles/Makefile2 core/libs/threadimageio/clean make[1] : on entre dans le répertoire « /mnt/devel/GIT/6.x/build » make -f core/libs/threadimageio/CMakeFiles/threadimageio_src.dir/build.make core/libs/threadimageio/CMakeFiles/threadimageio_src.dir/clean make[2] : on entre dans le répertoire « /mnt/devel/GIT/6.x/build » cd /mnt/devel/GIT/6.x/build/core/libs/threadimageio && /usr/bin/cmake -P CMakeFiles/threadimageio_src.dir/cmake_clean.cmake make[2] : on quitte le répertoire « /mnt/devel/GIT/6.x/build » make -f core/libs/threadimageio/CMakeFiles/threadimageio_src_automoc.dir/build.make core/libs/threadimageio/CMakeFiles/threadimageio_src_automoc.dir/clean make[2] : on entre dans le répertoire « /mnt/devel/GIT/6.x/build » cd /mnt/devel/GIT/6.x/build/core/libs/threadimageio && /usr/bin/cmake -P CMakeFiles/threadimageio_src_automoc.dir/cmake_clean.cmake make[2] : on quitte le répertoire « /mnt/devel/GIT/6.x/build » make[1] : on quitte le répertoire « /mnt/devel/GIT/6.x/build » [gilles@localhost threadimageio]$ make cd /mnt/devel/GIT/6.x/build && /usr/bin/cmake -H/mnt/devel/GIT/6.x -B/mnt/devel/GIT/6.x/build --check-build-system CMakeFiles/Makefile.cmake 0 cd /mnt/devel/GIT/6.x/build && /usr/bin/cmake -E cmake_progress_start /mnt/devel/GIT/6.x/build/CMakeFiles /mnt/devel/GIT/6.x/build/core/libs/threadimageio/CMakeFiles/progress.marks cd /mnt/devel/GIT/6.x/build && make -f CMakeFiles/Makefile2 core/libs/threadimageio/all make[1] : on entre dans le répertoire « /mnt/devel/GIT/6.x/build » make -f core/libs/threadimageio/CMakeFiles/threadimageio_src_automoc.dir/build.make core/libs/threadimageio/CMakeFiles/threadimageio_src_automoc.dir/depend make[2] : on entre dans le répertoire « /mnt/devel/GIT/6.x/build » cd /mnt/devel/GIT/6.x/build && /usr/bin/cmake -E cmake_depends "Unix Makefiles" /mnt/devel/GIT/6.x /mnt/devel/GIT/6.x/core/libs/threadimageio /mnt/devel/GIT/6.x/build /mnt/devel/GIT/6.x/build/core/libs/threadimageio /mnt/devel/GIT/6.x/build/core/libs/threadimageio/CMakeFiles/threadimageio_src_automoc.dir/DependInfo.cmake --color= make[2] : on quitte le répertoire « /mnt/devel/GIT/6.x/build » make -f core/libs/threadimageio/CMakeFiles/threadimageio_src_automoc.dir/build.make core/libs/threadimageio/CMakeFiles/threadimageio_src_automoc.dir/build make[2] : on entre dans le répertoire « /mnt/devel/GIT/6.x/build » [ 0%] Automatic moc for target threadimageio_src ...
