             Bug #: 14971
           Summary: Warn on = vs == typos in more contexts
           Product: clang
           Version: trunk
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: Frontend
        AssignedTo: unassignedclangbugs at nondot.org
        ReportedBy: matthewbg at google.com
                CC: llvmbugs at cs.uiuc.edu
    Classification: Unclassified

Clang just failed to catch this bug, but fortunately GCC spotted it:

     friend bool operator==(filtered_category_iterator X,
                            filtered_category_iterator Y) {
       return X.Current = Y.Current;

Our -Wparentheses catches this in the condition of an if statement, but
apparently not other boolean contexts.
