crash_1.erl:42: The specification for crash_1:empty/0 states that the function might also return crash_1:targetlist() but the inferred return is none()
crash_1.erl:45: Record construction #targetlist{list::[]} violates the declared type of field list::'undefined' | crash_1:target()
crash_1.erl:48: The call crash_1:get_using_branch2(Branch::maybe_improper_list(),L::'undefined' | crash_1:target()) contains an opaque term as 2nd argument when terms of different types are expected in these positions
crash_1.erl:50: The pattern <_Branch, []> can never match the type <maybe_improper_list(),'undefined' | crash_1:target()>
crash_1.erl:52: The pattern <Branch, [H = {'target', _, _} | _T]> can never match the type <maybe_improper_list(),'undefined' | crash_1:target()>
