Creator shows syntax error where there is none

Qt Creator 2.2.0 beta shows syntax errors (underlines them with red) with code that is actually correct. The code below triggers the bug.

{{
class Task {
private:
int mStartTime;
int mEndTime;

public:
bool overlaps(const Task& t) const

{ if (t.mStartTime == this->mStartTime or t.mEndTime == this->mEndTime) return true; if (t.mStartTime < this->mStartTime and t.mEndTime > this->mStartTime) return true; if (t.mStartTime < this->mEndTime and t.mEndTime > this->mEndTime) return true; if (t.mStartTime > this->mStartTime and t.mEndTime < this->mEndTime) return true; return false; }

};
}}
