Summary: Segfault during background parsing
Product: kdevelop
Version: unspecified
Platform: unspecified
OS/Version: Linux
Status: UNCONFIRMED
Severity: crash
Priority: NOR
Component: general
AssignedTo: kdevelop-bugs kdevelop org
ReportedBy: sputnick gmx net
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.
Backtrace from the first project (on open) follows:
Application: KDevelop (kdevelop), signal SIGSEGV
