            Bug ID: 21740
           Summary: Boolean operation always lvalue
           Product: clang
           Version: 3.5
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: Static Analyzer
          Assignee: kremenek at apple.com

    Classification: Unclassified

#include <stdio.h>
#include <stdbool.h>

int main() {
    bool expression_true = true;
    bool always_false = false;

    always_false &= expression_true;

    printf ("%d\n", always_false);

    return 0;

Should trigger a warning on the always_false operation. Bug 11510 refers to a
similar issue.
