Bug ID: 422219
Summary: Including <ranges> with active C++2a parser crashes
kdevelop
Product: kdevelop
Version: 5.5.1
Platform: Archlinux Packages
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Language Support: CPP (Clang-based)
Assignee: kdevelop-bugs-n...@kde.org
Reporter: j...@meinkes.com
Target Milestone: ---
SUMMARY
A file that includes ranges crashes kdevelop when the C++ profile is set to
c++2a.
STEPS TO REPRODUCE
1. Create a C++ project
2. Create a C++ file that contain the line #include <ranges>
3. Set the C++ Profile to c++2a (also happens when CMakeLists.txt contains
set(CMAKE_CXX_STANDARD 20) )
OBSERVED RESULT
Kdevelop starts to reparse the project and crashes at about 87%.
EXPECTED RESULT
Kdevelop reparses the project and treats it as C++20.
SOFTWARE/OS VERSIONS
