Well.. not really. That there is a known bug in the current Code Completion 
implementation, but you seem to crash even though the "safety counter" has 
detected that something is amiss.. I've only seen that bug under rather 
particular circumstances, but you say you get it whenever you type?? 
Hopefully David can have a guess what's wrong..

In the meantime, you might want to turn off automatic code completion in 
Project -> Project Options -> C++ support -> Code Completion
