<pre>This assertion is failing for me at head with this reduced repro (using a debug
build of clang):
$ cat repro.cc
template <typename>
class b {
__attribute__((target("avx"))) void c();
};
class B {
public:
__attribute__((target("avx"))) __attribute__((always_inline)) B();
};
template <typename d>
void b<d>::c() {
B a;
}
template class b<int>;
$ clang++ -c repro.cc
clang++: llvm-project/clang/include/clang/AST/GlobalDecl.h:45: void
clang::GlobalDecl::Init(const clang::Decl *): Assertion
`!isa<CXXConstructorDecl>(D) && "Use other ctor with ctor decls!"' failed.
