            Bug ID: 16074
           Summary: Warn on boolean conversion of arrays
           Product: clang
           Version: trunk
          Hardware: PC
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: Frontend
          Assignee: unassignedclangbugs at nondot.org
          Reporter: benny.kra at gmail.com

    Classification: Unclassified

GCC warns on this:

void foo(bool);

int main() {
  int arr[42];
  foo(arr);
}

bool.cpp:5:10: warning: the address of ‘arr’ will always evaluate as ‘true’
[-Waddress]

clang has this warning for functions "foo(main)", we should enable it for
arrays and other local pointers too.
