Description of problem: I have not yet found a minimum skeleton of code to reproduce the problem, but it seems to happen when parsing some very templated c++11 code. Even opening files that contain a certain type on construct in the project seems to crash kdevelop. From the backtrace it seems to be a problem parsing the template specializations in the files in question. I will attempt to widdle down the code to something that reproduces the crash and append it to this ticket.

Created attachment 783988 [details] Crashing c++11 source This code when CMakeLists.txt has set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11") will crash KDevelop's parser
The crash seems to come from template specializations when the template declaration is not available in the file with the specialization. If I delete the DataSource<double> specialization, I can recreate the crash by typing that definition up to the DataSource keyword. If the file is already loaded then I can cause a crash by typing the template keyword anywhere in the file. Note the c++11 source in crash.cpp does not crash if the template forward declaration is uncommented. It will still crash if that forward declaration is located in another file. This code is valid c++11.
This message is a notice that Fedora 19 is now at end of life. Fedora has stopped maintaining and issuing updates for Fedora 19. It is Fedora's policy to close all bug reports from releases that are no longer maintained. Approximately 4 (four) weeks from now this bug will be closed as EOL if it remains open with a Fedora 'version' of '19'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 19 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
