*** Bug 250390 has been marked as a duplicate of this bug. *** if either of you is able to reproduce it, please run kdevelop in valgrind and give us the log. Run this: kdevelop --session => copy'n'paste the hash for your session. Than do this: KDEV_SESSION=$session valgrind --track-origins=yes kdevelop.bin reproduce the rash and send me the output of valgrind. Short extract from valgrind, cannot reproduce the crash actually (it is still parsing the files in the background however, I'll try again later), the first invalid read with size 1 happened repeatedly and filled my console backlog, I'll probably try to pipe it into a file later. ==8497== Invalid read of size 1 ==8497== at 0x4C2991F: memcpy (mc_replace_strmem.c:497) ==8497== by 0x293CE512: Konsole::TerminalDisplay::updateImage() (in /usr/lib/libkonsoleprivate.so) ==8497== by 0x293D0E1D: Konsole::TerminalDisplay::qt_metacall(QMetaObject::Call, int, void**) (in /usr/lib/libkonsoleprivate.so) ==8497== by 0x624BB26: QMetaObject::activate(QObject*, QMetaObject const*, int, void**) (qobject.cpp:3280) ==8497== by 0x293A9165: ???

Seems to be fixed here, thanks! thanks again for your help, without your valgrind logs it wouldn't have been possible! *** Bug 255628 has been marked as a duplicate of this bug. *** Heya, can you please point me a to a patch that fixed the issue? We're having similar problem in Amarok bug 265626 comment 32 and I don't want to reinvent the wheel. ID: b802735c2b2b8810a8b901f93bbcd97519c0c9cd Added by Milian Wolff almost 4 years ago fix: use QueuedConnection to fix crash on show declaration/definition the problem is that quite some direct connections eventually lead to a call to MainWindowPrivate::mergeView() which in turn called KXMLGuiFactory::removeClient which deleted the QMenu. Afterwards the menu is closed but was already deleted => boom BUG: 249884 https://projects.kde.org/projects/extragear/kdevelop/kdevplatform/repository/revisions/b802735c2b2b8810a8b901f93bbcd97519c0c9cd Sorry, I don't know why this wasn't added automatically, or why I did not read your email earlier. Hope it helps. |
