Hmm, Clang also rejects this test:

t.cc:12:7: error: call to constructor of 'Foo' is ambiguous
  Foo foo1({{"abc", {"aaa"}}});         // Error.
      ^    ~~~~~~~~~~~~~~~~~~
t.cc:5:8: note: candidate is the implicit move constructor
struct Foo {
       ^
t.cc:5:8: note: candidate is the implicit copy constructor
t.cc:6:3: note: candidate constructor
  Foo(const std::map<std::string, std::vector<std::string>>&);
  ^
1 error generated.


I must have over-reduced the original.
