Application: kdevelop (5.2.3) Qt Version: 5.11.1 Frameworks Version: 5.48.0 Operating System: Linux 4.17.10-1-ARCH x86_64 Distribution: "Arch Linux" -- Information about the crash: - What I was doing when the application crashed: I opened a project. The background parser started then crashes the IDE. It happen every time I open that particular project. This make KDevelop completely unusable for that project (cash on startup) Some investigation showed me that it happen when the cursor kind is CXCursor_FunctionTemplate and it seem it happen when it's a member function. I tried debugging it but it was inconclusive. Copying the preprocessed file in another project did not reproduced the crash. I Also tried deleting the .kdev and the .kdev folder and I tried emptying the cache. - Custom settings of the application: I enabled C++17. It didn't seemed related for this bug however. It happen both with the master branch and the v5.2.3 tag The crash can be reproduced every time. -- Backtrace: Application: KDevelop (kdevelop), signal: Segmentation fault Using host libthread_db library "/usr/lib/libthread_db.so.1".

/usr/lib/libQt5Core.so.5 #48 0x00005611538a5278 in main(int, char**) (argc=2, argv=0x7ffe8f922e58) at /home/master/prog/kdevelop/app/main.cpp:793 Reported using DrKonqi
I tried opening the project in QtCreator, and it cannot parse the project correctly. I get in the console "Clang Code Model: Error: The clangbackend process has finished unexpectedly and was restarted." So it seems to be an error in the clang library. But instead of outputting an error like QtCreator, kdevelop crashes.
Yeah, because KDevelop runs clang in-process.

Created attachment 115046 [details] New crash information added by DrKonqi kdevelop (5.2.4) using Qt 5.11.1 - What I was doing when the application crashed: After having issues with the parser not working correctly, I attempted to clear the cache and restart KDevelop. Reparsing of the project then commenced, and after a while it crashes. Sometimes instantly, sometimes after some parsing progress. Happens 7/7 times. - Unusual behavior I noticed: Before this happened, KDevelop crashed once or twice. Clearing the cache did the trick then, but it no longer works. Also, the parser has been working very badly. It doesn't recognize most header files, even though include paths are set for the project. It also misidentifies some classes as being part of the "std::"-namespace for the headers that are recognized. So if I for example declare `class Foo` in Foo.hpp, then I will get parser errors on usages of this class that suggest that I change them to std::Foo instead, (message says: did you mean std::Foo? Solutions: include Foo.hpp) - Custom settings of the application: Session has 3 projects. All are configured with regular makefiles, and uses gcc with the C++17 standard for compilation. The parser uses clang with the -std=c++17 flag. One of the projects also uses libclang as a dependency for static code generation. All KDE applications are installed via official Arch Linux repository. -- Backtrace (Reduced): #6 0x00007fea5f993450 in clang::Decl::setInvalidDecl(bool) () at /usr/lib/../lib/libclangAST.so.6 #7 0x00007fea5f99349c in clang::Decl::setInvalidDecl(bool) () at /usr/lib/../lib/libclangAST.so.6 #8 0x00007fea58dddbc8 in clang::ASTDeclReader::VisitDecl(clang::Decl*) () at /usr/lib/../lib/../lib/libclangSerialization.so.6 #9 0x00007fea58dde482 in clang::ASTDeclReader::VisitNamedDecl(clang::NamedDecl*) () at /usr/lib/../lib/../lib/libclangSerialization.so.6 #10 0x00007fea58dde982 in clang::ASTDeclReader::VisitValueDecl(clang::ValueDecl*) () at /usr/lib/../lib/../lib/libclangSerialization.so.6
The crash still happens with clang 7.

It seems the crash now has a workaround. When opening the crashing project, I click the "Stop All" button as soon as the initial parsing starts. Then, everything seems to work at that point.
