--- Comment #4 from Kevin Funk <kf...@kde.org> --- Okay, you got me curious. Indeed the issue can't be Qt5 (which I initially presumed it is), since on Ubuntu Zesty i386 it is in fact compiled without SSE2 support: See build log: https://launchpadlibrarian.net/305749426/buildlog_ubuntu-zesty-i386.qtbase-opensource-src_5.7.1+dfsg-2ubuntu4~1_BUILDING.txt.gz from https://launchpad.net/~ci-train-ppa-service/+archive/ubuntu/2454-deletedppa/+build/11985181 So feel free to investigate further -- I can imagine Clang/LLVM being the other possible cause. Try to check which library KDevelop attempts to loads before crashing, e.g. by invoking this: LD_DEBUG=files kdevelop -- You are receiving this mail because: You are watching all bug changes.
