Since a205695 landed, the following templated attribute((constructor)) hello world test case will crash clang:

extern "C" int printf(const char *, ...);

template <typename C, void (C::*F)(void) const>
__attribute__((constructor)) void baz() { (C().*F)(); }

struct B {
  B() {
   struct A {
      void foo() const { printf("hello world!\n"); }
      void bar() const {
         ::baz<A, &A::foo>();
      }
   };
  }
};

int main() {
  return 66;
}

Expected:

$ /home/daltenty/llvm/dev/build/bin/clang++ test.cc
$ ./a.out
hello world!
$ echo $?
66

Actual:

/home/daltenty/llvm/dev/build/bin/clang++ test.cc
