           Summary: Comma sub-expr in do-while loop conditional not
                    evaluated
           Product: clang
           Version: 3.0
          Platform: PC

    Classification: Unclassified


The first sub-expression of a comma operator in a do-while conditional is not
evaluated.

Compile the following C++ program:

#include <iostream>

int main()
{
    int i = 0;
    do
        ;
    while (i = 1, false);
    std::cout << i << std::endl;
}

The program output '0'.

The program should output '1'.
