In none of those cases I could see a crash, so it's clearly not happening to everyone and thus I'm lowering the severity. It is however something we need to triage for buster. > This is what I get when I try to start qtcreator: > > Program received signal SIGSEGV, Segmentation fault. > 0x00007fffe6091e3c in llvm::SmallPtrSetImplBase::Grow(unsigned int) () > from /usr/lib/x86_64-linux-gnu/libLLVM-3.7.so.1 OK, so LLVM involved. > Complete backtrace, as from gdb: > > #0 0x00007fffe6091e3c in llvm::SmallPtrSetImplBase::Grow(unsigned int) () > from /usr/lib/x86_64-linux-gnu/libLLVM-3.7.so.1 > #1 0x00007fffe6091ff3 in llvm::SmallPtrSetImplBase::insert_imp(void const*) > () from /usr/lib/x86_64-linux-gnu/libLLVM-3.7.so.1 > #2 0x00007fffe6060d24 in llvm::cl::OptionCategory::registerCategory() () > from /usr/lib/x86_64-linux-gnu/libLLVM-3.7.so.1 > #3 0x00007fffd7602082 in ??

I need some extra info: - Which video card are you using? - Please create a new user and try starting qtcreator there. Moving out Qt creator's config is also possible, but more involved: you need to move ~/.config/QtCreatorrc *and* ~/.config/QtProject/qtcreator/ *and* ~/.config/QtProject/QtCreator* (without qtcreator running) and then start it. - Have you installed any third party plugin? The crash seems to come from loading a plugin. Thanks for your report and your help, Lisandro. -- Lisandro Damián Nicanor Pérez Meyer http://perezmeyer.com.ar/ http://perezmeyer.blogspot.com/
