use keyword "typedef" cause QtCreator crash

Hi, this the the bug. (it is in QtCreator 2.4.1 too)
1. create an empty project or open any project.
2. input some code like this(anywhere):

typedef (*TESTFUNC)()
{
}

3. now when you move anchor to the first line, the QtCreator will crash.
I lose my code before I save them... T-T
