As of r147790, clang still crashes on the following line of code, if
-W[no-]address-of-temporary is used:


$ cat bug.cc
int (*pa)[1] = &(int[]) { 1 };


$ clang++ -c bug.cc
bug.cc:1:16: error: taking the address of a temporary object of type
'int [1]'
      [-Waddress-of-temporary]
int (*pa)[1] = &(int[]) { 1 };
               ^~~~~~~~~~~~~~
1 error generated.


$ clang++ -Waddress-of-temporary -c bug.cc
bug.cc:1:16: warning: taking the address of a temporary object of type
'int [1]'
      [-Waddress-of-temporary]
int (*pa)[1] = &(int[]) { 1 };
               ^~~~~~~~~~~~~~
