//  Purpose:

//  Discussion:
//
//    VALGRIND's MEMCHECK program monitors uninitialized variables, but does
//    not complain unless such a variable is used in a way that means its
//    value affects the program's results, that is, the value is printed,
//    or computed with.  Simply copying the unitialized data to another variable
//    is of no concern.
