Version: 3.9.0 (using 4.1.60 (KDE 4.1.60 (KDE 4.2 >= 20080709)), Gentoo) Compiler: i686-pc-linux-gnu-gcc OS: Linux (i686) release 2.6.25-gentoo-r3 On opening a project of mine (which worked fine with kdev4 from about 2 weeks ago), kdev crashes during the background parses. Another of my projects I can open fine, but adding an attribute to a class leads to the same crash. Disabling background parsing resolves this crash. I have just upgraded both kdevplatform and kdevelop (and most if not all of the rest of KDE), and I can reproduce the issue on two machines. Output immediately before crashing: kdevelop(22554)/kdevelop (cpp duchain) DeclarationBuilder::visitEnumerator: not assigned enumerator type kdevelop(22554)/kdevelop (cpp duchain) DeclarationBuilder::visitEnumerator: not assigned enumerator type kdevelop(22554)/kdevelop (cpp duchain) DeclarationBuilder::visitEnumerator: not assigned enumerator type kdevelop(22554)/kdevplatform (language) KDevelop::SymbolTable::removeDeclaration: Could not find declaration matching "" Program received signal SIGSEGV, Segmentation fault.

Reproducable with Quassel's source: git clone git://git.quassel-irc.org/quassel.git Import this as a cmake project and open it. After that, open chatitem.h and try adding an attribute to the class. I can reproduce the crash 100% of the time by trying to add "int debugflg" to the private section of class ChatItem. If that doesn't help, please ping me again ("Sput" on IRC) so I can try to find another testcase.
Adding David to Cc as I can't reproduce this. David let me know if you're reading kdevelop-bugs regurlarly, then I can stop adding you to the Cc.

I've downloaded the project, and tried what you said. Could not reproduce the problem though. Maybe a mis-compilation? Try rebuilding kdevplatform + kdevelop completely.
Have rebuilt everything completely, also removed my config files just to be sure, and I can still reproduce this on both machines with both projects :/ Also I've found out that with background parsing enabled, it doesn't even matter what I type where. Just entering anything anywhere in an open file leads to the crash after a few seconds.

OK, compiling kdevplatform in debug mode, I seem to be able to start kdevelop most of the time and have a project open without crashing, whereas in release mode, apparently I can reproduce a segfault in smartRange() every time... This is true even with background parsing enabled, i.e. with kdevplatform in debug mode, I can successfully open the project most of the time, including all features. To make things more interesting, with this configuration and that same project, I still get regular crashes on startup that seem to be unrelated to above bug: #0 0xb6493454 in _int_malloc () from /lib/libc.so.6 #1 0xb649498e in malloc_check () from /lib/libc.so.6 #2 0xb6495415 in malloc () from /lib/libc.so.6 #3 0xb664a1c9 in operator new () from /usr/lib/gcc/i686-pc-linux-gnu/4.2.4/libstdc++.so.6 #4 0xb6359863 in QList<KDevelop::QualifiedIdentifier>::node_construct (this=0xb081da18, n=0xa143a9c, t=@0xb081d8d0) at /usr/include/qt4/QtCore/qlist.h:338 #5 0xb6359aed in QList<KDevelop::QualifiedIdentifier>::append (this=0xb081da18, t=@0xb081d8d0) at /usr/include/qt4/QtCore/qlist.h:424 #6 0xb6359b19 in QList<KDevelop::QualifiedIdentifier>::operator<< (this=0xb081da18, t=@0xb081d8d0) at /usr/include/qt4/QtCore/qlist.h:302 #7 0xb634a95b in KDevelop::DUContext::SearchItem::toList (this=0xb18ca50, prefix=@0xb081da08) at /var/tmp/portage/kde-base/kdevplatform-9999/work/kdevplatform-9999/language/duchain/ducontext.cpp:1519 #8 0xb18ec65b in Cpp::CppDUContext<KDevelop::TopDUContext>::findDeclarationsInternal () from /usr/kde/svn/lib/libkdev4cppduchain.so #9 0xb193e103 in DelayedTypeResolver::exchange () from /usr/kde/svn/lib/libkdev4cppduchain.so #10 0xb1937cb8 in Cpp::resolveDelayedTypes () from /usr/kde/svn/lib/libkdev4cppduchain.so #11 0xb18ebe88 in Cpp::CppDUContext<KDevelop::TopDUContext>::findDeclarationsInternal () from /usr/kde/svn/lib/libkdev4cppduchain.so #12 0xb18ec713 in Cpp::CppDUContext<KDevelop::TopDUContext>::findDeclarationsInternal () from /usr/kde/svn/lib/libkdev4cppduchain.so #13 0xb634b869 in KDevelop::DUContext::findDeclarations (this=0xab162a8, identifier=@0xb081e958, position=@0xb081e950, dataType=@0xb081e974, topContext=0xab162a8, flags=@0xb081e970) at /var/tmp/portage/kde-base/kdevplatform-9999/work/kdevplatform-9999/language/duchain/ducontext.cpp:704 #14 0xb190bf6e in TypeBuilder::openTypeFromName () from /usr/kde/svn/lib/libkdev4cppduchain.so #15 0xb190cfbb in TypeBuilder::visitSimpleTypeSpecifier () from /usr/kde/svn/lib/libkdev4cppduchain.so #16 0xb187ef87 in Visitor::visit () from /usr/kde/svn/lib/libkdev4cppparser.so #17 0xb190b9e9 in TypeBuilder::visitSimpleDeclaration () from /usr/kde/svn/lib/libkdev4cppduchain.so #18 0xb18f0b6b in DeclarationBuilder::visitSimpleDeclaration () from /usr/kde/svn/lib/libkdev4cppduchain.so #19 0xb187ef87 in Visitor::visit () from /usr/kde/svn/lib/libkdev4cppparser.so #20 0xb187dee8 in visitNodes<DeclarationAST*> () from /usr/kde/svn/lib/libkdev4cppparser.so #21 0xb187ef87 in Visitor::visit () from /usr/kde/svn/lib/libkdev4cppparser.so #22 0xb18e14dc in ContextBuilder::startVisiting () from /usr/kde/svn/lib/libkdev4cppduchain.so #23 0xb18f8dc0 in KDevelop::AbstractTypeBuilder<AST, NameAST, ContextBuilder>::supportBuild () [...]

@Ian Monroe: Please update kdevplatform and kdevelop and try again, and re-post the backtrace if you still get the crash. The problem is that your line-numbers are totally off, and it looks like your version is from before many changes in that Area.
I can still reproduce that one with kdevplatform in release mode. Still works fine in debug mode. Current backtrace follows; note how it looks different from the original one now, but still crashes at the same location...

Backtrace in comment 11 looks similar to the one in bug 176380.
The crash reported in the last comment was most probably one of the release/debug problem crashes, that are fixed now, so I'm closing. If you encounter it again, reopen.
