           Summary: Lvalue transformation not ignored when parameter is a
                    const-reference
           Product: clang
           Version: trunk
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: C++0x
        AssignedTo: unassignedclangbugs at nondot.org
        ReportedBy: schaub.johannes at googlemail.com

This should be ambiguous (the array to pointer conversion for the first
candidate should not make the candidate worse than the second one):

void f(int * const&);
void f(int const(&)[1]);

int main() {
  int n[1];
  f(n);
}

Clang takes the second one. If we make the parameter of the first a "int *",
Clang behaves as expected.
