DUChain crash, reparsing cpp/parser/parser.cpp

[Andreas Pakulat]

Hi,

this happened after removing a (manually added) duplicate of the
hashed-string include at the end of includes. So after removing the
duplicate include kdevelop started to reparse the file and crashed close
to the end. I'll leave the core file around in case more frames/threads
are needed.
