CLI debug output 

Version:           git master (using KDE 4.5.5) 
OS:                Linux

When trying to parse the file boost/mpl/assert.hpp (from Boost 1.47, haven't
tried older versions yet) the expression parser crashes. Here is what print
m_session->dumpNode(node) in Cpp::ExpressionVisitor::visit gives

 SimpleTypeSpecifier [ 166 , 167 ] "assert_ " 
   Name [ 166 , 167 ] "assert_ " 
     UnqualifiedName [ 166 , 167 ] "assert_ " 
     UnqualifiedName 
   Name 
 SimpleTypeSpecifier 

and here's the backtrace

I'll also attach the CLI output and the offending header file. kdevduchain and
configuration in .kde had been cleared previously.

Reproducible: Always

Steps to Reproduce:
Open boost/mpl/assert.hpp (from boost 1.47) in kdevelop

Actual Results:  
Crash

Expected Results:  
No crash
