No, it doesn't. This is not a initialization followed by an assignment
operator; there is no assignment operator at all in this statement.
Instead, it is a copy-initialization, which invokes the copy
constructor.

The difference between initialization and assignment should be
explained in every C++ text book. In the C++ standard, it is defined
in section 8.5, [dcl.init]/12.
In short: you program is well-formed, and the compiler is correct in
accepting it; this is not a bug.
