Carlo has a great reason for that: he needs to run demangle_type from 
malloc().

I agree fully. Why not keep the user-friendly interface and add an overload 
with an allocator parameter?

  template<typename Allocator>
  std::basic_string<char, std::char_traits<char>, Allocator>
  demangle_type(const std::type_info& type, const Allocator& allocator);

  // simpler non-template versions use the default allocator
  std::string demangle_type(const std::type_info& type);

  // also provide overloads where the first parameter is an std::string or
  // const char*
