In the following program...
==========
#include <stdio.h>
// Should not be here to create syntax error
#include <stdarg.h>
int main(void *var[], va_list ap) {
  int i=0;
  void *v;
  for (;;)
    v = va_arg(ap, void *); //extract statement
  return 0;
}
==========

If we remove the inclusion of stdarg.h, then there is a syntax error in the va_arg line. So, then if you try to extract, CDT throws the following exception:

 [ERROR] org.eclipse.cdt.internal.core.dom.rewrite.astwriter.ProblemRuntimeException

at org.eclipse.cdt.internal.core.dom.rewrite.astwriter.ASTWriterVisitor.visit(ASTWriterVisitor.java:189)

When you include the file, the syntax error is resolved, and the refactoring does not have a problem. 
May be a bug only because the refactoring should not throw an exception.
