It's also possible to have minimal symbols with different mangled
names, but identical demangled names. For example, the GNU C++ v3
ABI requires the generation of two (or perhaps three) copies of
constructor functions --- "in-charge", "not-in-charge", and
"allocate" copies; destructors may be duplicated as well.
Obviously, there must be distinct mangled names for each of these,
but the demangled names are all the same: S::S or S::~S. */
