Description Farnaz Behrang CLA 2012-12-11 21:16:31 EST 
In the following program...
==========
int main(){
  enum {
    EN1 = 0,
    EN2,
  } enum_var;
  enum_var = -1; //select statement without ;
  return 0;
}
==========

If you select enum_var = -1 (on line 5), and invoke the Extract Function refactoring, CDT throws the ClassCast Exception.

Part of the trace:

[ERROR] java.lang.ClassCastException: org.eclipse.cdt.internal.core.dom.parser.c.CNodeFactory cannot be cast to org.eclipse.cdt.core.dom.ast.cpp.ICPPNodeFactory
