Bug ID: 409747
Summary: Crash + data loss
Product: kdevelop
Version: 5.3.1
Platform: Other
OS: Linux
Status: REPORTED
Severity: crash
Priority: NOR
Component: Code completion
Assignee: kdevelop-bugs-n...@kde.org
Reporter: w0...@mail.com
Target Milestone: ---
Kdevelop crashed in libclang while auto-completing. The biggest issue is that
after crashing, the entire file I was working on was deleted (the file has a
size 0 on disk). Unfortunately those crashes seem kind of random and very hard
to reproduce.
