[cfe-commits] [Patch] Warn about self-init of refs using parenthesized initializers

[Hans Wennborg]

Hi,

As pointed out in Wei's email [1], Clang currently fails to warn about
self-initialized references when using parenthesized initializers:

  void f() {
    int &a(a);
  }

The attached patch fixes this. Please take a look.

Thanks,
Hans
