Does this problem persist after you remove ~/.kdevduchain?
This looks rather fishy, esp. considering that it crashes in a dynamic cast. The code is:
static DUChainPointer<ClassDeclaration> exceptionDecl;
if (!exceptionDecl) {
QList<Declaration*> decs = dec->context()->findDeclarations(QualifiedIdentifier("exception"));
Q_ASSERT(decs.count() == 1);
exceptionDecl = dynamic_cast<ClassDeclaration*>(decs.first());
Q_ASSERT(exceptionDecl);
}
Anyone else an idea what might be happening?
I'll try to reproduce at home, though I'm pretty sure that it once worked fine...
Just compiled at work and tried your example: Works fine. Does this also happen in other files? Might happen if you use multithreading and don't lock the duchain before calling findDeclarations, as the declarations may already be deleted when you try to cast them. It's locked, and ENSURE_CAN_READ would abort else. Hi! Tomorrow (2010.03.16) I'll try to reproduce on a code what i can share with you and will attach here. Maybe the error accours on my specific code. Hi! Today morning, i completly removed all installed binary, build directories and my working copy. Checked out source again and re-compiled everything. Now the autocomplete works at that point. Thanks for your time guys, next time i'll start with this. Cheers |
Application: kdevelop (3.9.99 (using KDevPlatform 0.9.99)) KDE Platform Version: 4.4.1 (KDE 4.4.1) (Compiled from sources) Qt Version: 4.6.2 Operating System: Linux 2.6.32-sabayon x86_64 Distribution: "Gentoo Base System release 2.0.1" -- Information about the crash: I'm guessing the autocompleter crashing. I tried declare a class, but the app chrased after "extends" keyword. It repeated all time. So what exactly i timed: class cache_memcache extends <- so here when i push space here, app crashing. I'm using SVN version 1102348 i think. Compiled by myself (not portage). The crash can be reproduced every time. -- Backtrace: Application: KDevelop (kdevelop.bin), signal: Segmentation fault Traceback (most recent call last): File "/usr/share/gdb/auto-load/usr/lib64/libgobject-2.0.so.0.2200.3-gdb.py", line 9, in <module> from gobject import register File "/usr/share/glib-2.0/gdb/gobject.py", line 3, in <module> import gdb.backtrace ImportError: No module named backtrace [Current thread is 1 (Thread 0x7fa830cee750 (LWP 13635))] Thread 6 (Thread 0x7fa81af40910 (LWP 13636)): #0 0x00007fa82d37524d in pthread_cond_timedwait@@GLIBC_2.3.2 () from /lib/libpthread.so.0 #1 0x00007fa82d6001f2 in QWaitCondition::wait(QMutex*, unsigned long) () from /usr/lib64/qt4/libQtCore.so.4 #2 0x00007fa82a29826e in KDevelop::DUChainPrivate::CleanupThread::run (this=0x1248c80) at /usr/local/src/kdesdk4/kdevplatform/language/duchain/duchain.cpp:286 #3 0x00007fa82d5ff2c5 in ??
