Application: kdevelop (5.3.40) (Compiled from sources) Qt Version: 5.11.1 Frameworks Version: 5.50.0 Operating System: Linux 4.15.0-33-generic x86_64 Distribution: KDE neon User Edition 5.13 -- Information about the crash: - What I was doing when the application crashed: 1. Project -> Prune Selection 2. Project -> Configure Selection 3. Project -> Open Configuration... 4. Enable custon "test" cmake option 5. Click on OK -> segfault I used this CMakeLists.txt ================== cmake_minimum_required(VERSION 3.5) project(crash) option(test "build tests" OFF) add_library(crash source/lib.cpp ) if(test) add_executable(unittest test/test.cpp) target_link_libraries(unittest PRIVATE crash pthread) endif(test) ================== source/lib.cpp ================== int add(int a, int b) { return a + b; } ================== test/test.cpp ================== int main() { return 0; } ================== It seems some ProjectFolderItems are created and added to the queue in FileManagerListJob. Then all ProjectFolderItem are deleted and when the next FileManagerListJob::startNextJob() accesses an element in the queue it's a dangling pointer and segfaults. I could track the issue to AbstractFileManagerPlugin::import. The KDirWatch item is still connected to the project path. When CMakePreferences::configure() triggers a reload, the KDirWatch triggers FileManagerListJob::startNextJob() but the ProjectFolderItems are also deleted. I could fix the problem by diconnecting all slots from KDirWatch for the given project, they are connected anyway when reloadModel triggers an import. I did this from CMakePreferences::configure() through the varius abstraction layers up to AbstractFileManagerPlugin. Don't know if this is a viable solution. Someone with more insight has to make a proper fix. The crash can be reproduced every time. -- Backtrace: Application: KDevelop (kdevelop), signal: Segmentation fault Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
