related valgrind output
crash is reproducible when run under valgrind and gives the attached valgrind output
*** Bug 262718 has been marked as a duplicate of this bug. *** *** Bug 269761 has been marked as a duplicate of this bug. *** Thanks for the valgrind log, this seems to be a real issue. Can anyone of you give us access to the file/project that triggers this issue? Maybe look at the output of kdevelop and see what file is parsed/highlighted before it crashes (see also the kdebugdialog app to enable kdev c++ and language debug areas). @David: Looking at the sources I see that the DUChain is repeatedly locked/unlocked in CodeHighlightingInstance but the API uses raw pointers, not DUChainPointers, which might lead to problems like this one, or? Though considering that the ReferencedTopDUContext in CodeHighlighting::highlightingDUChain is kept alive, the document should not be cleaned/invalidated inbetween hmmm.... The duchain of the document should not be changed while updating, because the parse-job triggering the highlighting is holding the UrlParseLock for the document and the parseLock of the language-support. One prevents updating of the document, the other one prevents a global cleanup of the duchain. Still, maybe this doesn't work properly. @reporter: Please remove the "lock.unlock();" line in CodeHighlighting::highlightDUChain, rebuild, and check if the crash still happens. Hello, there is still this issue. I have compiled kdevelop from sources 2 hours ago. I am using gentoo as my distro. i have made some tests,kdevelop is working for 3 template projects but when i add plasmate in the list it crashes... My intention is to give you more feedback and not to complain about the bug.. Here is the latest output, Application: KDevelop (kdevelop), signal: Segmentation fault [Current thread is 1 (Thread 0x7f0c437fa760 (LWP 438))] Thread 13 (Thread 0x7f0c2e910700 (LWP 1789)): #0

more feedback,please let me know. ah, this is a duplicate report. also note that I fixed 284536 just a few minutes ago - please try to update and see if it still crashes. thanks *** This bug has been marked as a duplicate of bug 284536 *** kdevelop-4.2.3 doesn't crash. The master(after milian's patch) is still crashing Tsiapaliwkas: Please show an updated backtrace of master crashing and attach that information to bug 284536 the bug indicated by above backtrace is definitely fixed. *** Bug 289455 has been marked as a duplicate of this bug. *** This isn't a duplicate of bug 284536, as that clearly indicates a complete different backtrace.

I'll look into it now. Minimal testcase I could come up with so far:
// add a comma after T here and wait and/or save and press f5
template<typename T>
class foo
{
template<typename Tn>
void bar()
{
}
template<typename Tn>
void asdf()
{
decltype(((foo<T>*)nullptr)->bar<Tn>());
}
};

Committed on 17/11/2013 at 02:08. Pushed by mwolff into branch '4.6'. Do not delete anonymous contexts of instantiations. This "fix" is ugly, but similar to what was done before in the declaration builder which we happily live with since years. So, better than crashing, lets workaround this nasty issue.
