<pre>On the following input file, the static analyzer reports a "Called C++ object
pointer is null" warning, even though the offending statement is never reached,
since the destructor of A never returns.
$ cat a.cc
struct Fatal { ~Fatal() __attribute__((noreturn)); };
struct A { void a(); };
void f(A* a) {
a ? (void) 0 : (void)Fatal();
a->a();
}
$ ~/llvm/build/bin/clang --analyze a.cc
a.cc:7:3: warning: Called C++ object pointer is null
a->a();
^~~~~~
1 warning generated.</pre>
