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....
