           Summary: placement new with vexing parse parsed as ill-formed
                    non-placement new
           Product: clang
           Version: trunk
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: C++
        AssignedTo: unassignedclangbugs at nondot.org
        ReportedBy: richard-llvm at metafoo.co.uk

clang rejects this:

using size_t = decltype(sizeof(int));
struct S {};
void *operator new(size_t, S);
void f() { new (S()) int; }

foo.cpp:4:17: error: cannot allocate function type 'S ()' with new
void f() { new (S()) int; }
                ^~~

The standard does not appear to provide any guidance in disambiguating this
case, but g++-4.4.5 accepts it, and it seems reasonable for us to do the same.
