errors on std::uninitialized_xxx<volatile T*>
---------------------------------------------

         Key: STDCXX-203
         URL: http://issues.apache.org/jira/browse/STDCXX-203
     Project: C++ Standard Library
        Type: Bug

  Components: 20. General Utilities  
    Versions: 4.1.2, 4.1.3    
 Environment: all
    Reporter: Martin Sebor
 Assigned to: Martin Sebor 
     Fix For: 4.2


The following doesn't compile. It should, even if the current standard currently says it's
ill-formed.

$ cat t.cpp && gmake t
#include <memory>

int main ()
{
    volatile int i;

    std::uninitialized_copy (&i, &i, &i);
    std::uninitialized_fill (&i, &i, 0);
    std::uninitialized_fill_n (&i, 0, 0);
}
