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);
}
