Since a205695de4dce3c839dedbb78dd67e2a7758947a 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
