Summary: KDevelop always crashes when loading session cache
Classification: Applications
Product: kdevelop
Version: git master
Platform: Gentoo Packages
OS: Linux
Status: REPORTED
Severity: crash
Priority: NOR
Component: Language Support: CPP (Clang-based)
Assignee: kdevelop-bugs-n...@kde.org
Reporter: eugene.shalygin+bugzilla....@gmail.com
Target Milestone: ---
SUMMARY
KDevelop, built against LLVM 17.0.6, always crashes when loading existing
session cache.
STEPS TO REPRODUCE
1. Load a project, wait for it to be parsed.
2. Close KDevelop.
3. Re-open KDevelop with this session, without clearing duchain cache or
reparsing project on opening enabled.
OBSERVED RESULT
