the cherry-pick seems to have patched the "wrong" function,
get_unique_hashed_string instead of get_unique_type_string which is mentioned
by the ChangeLog but not touched. get_unique_type_string looks still broken
in this respect, and we run into
Breakpoint 5, get_unique_type_string (string=0x7fffffffd610 "@\302\031\003",
derived=0x320d8a0)
