Bug ID: 379669
Summary: KDevelop continues to hang on exit in itemrepository.h
Product: kde
Version: unspecified
Platform: unspecified
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: unassigned-bugs at kde.org
Reporter: rjvbertin at gmail.com
Target Milestone: ---
Application: kdevelop5 (5.1.0)
(Compiled from sources)
Qt Version: 5.8.0
Frameworks Version: 5.32.0
Operating System: Linux 4.9.8-ck1-mainline-core2-rjvb x86_64
Distribution: Ubuntu 14.04.5 LTS
-- Information about the crash:
- What I was doing when the application crashed:
I don't recall what I had been doing in KDevelop, but when done I quit the
application. An hour later I realised my fan was still blowing, and I
discovered the KDevelop process burning 100% CPU.
The crash ensued when I terminated the process via KSysguard5.
This is a long-standing issue that somehow has become more frequent now that I
use libclang 4.0 for the C/C++ parser. The only still open ticket about it
concerns KDevelop 4.x and is thus no longer relevant (and besides DrKonqi won't
let me attach this information to that ticket). I'm opening a new ticket.
The only way I know to reproduce the issue is NOT to cross fingers that
KDevelop will really exit.
I wonder: does this finalCleanup() have any lasting side-effects like cleaning
up the on-disk cache, instead of just returning memory to the system that will
be returned anyway? If not, why not simply skip the step and let the runtime
return all memory to the system?
Alternatively, couldn't this be run earlier, before the global destruction
phase, for instance in reaction to QCoreApplication::aboutToQuit()?
The crash can be reproduced sometimes.
-- Backtrace:
