Description Sergey Prigogin CLA 2010-08-05 18:26:38 EDT 
CDT HEAD:

int& func();

#define X func() = 1

void test() {
  X;  // The line is marked: Assignment to itself 'X'
}
Comment 1 Elena Laskavaia CLA 2010-08-05 22:53:46 EDT 
did not know you can write programs like this... 

Simpler case
#define X a = 1

main(){
  X;
}

(In reply to comment #1)

This is not the actual code on which I encountered the problem initially. The problem affects assertion macros of googletest (http://code.google.com/p/googletest/) framework.
Comment 3 Elena Laskavaia CLA 2010-08-06 21:53:57 EDT 
fixed on head (8.0) test case added
