            Bug ID: 222562
           Summary: c++filt and libelftc do not demangle names correctly
           Product: Base System
           Version: CURRENT
          Hardware: Any
                OS: Any
            Status: New

Small c++ program to demonstrate the problem

If you compile the attached tester.cc source (just "make tester.o") then use
nm(1) on the .o file, the nm output includes two mangled symbol names:

00000000 V _ZTS3Foo
00000000 r _ZTSZ4mainE3Bar

Running them through c++filt gives:=20

# c++filt _ZTS3Foo _ZTSZ4mainE3Bar
typeinfo name for Foo
_ZTSZ4mainE3Bar

(The program also produces wrong output when it runs, but that will be hand=
led
in a separate PR, becuase our current libcxxrt uses different demangling co=
de
than libelftc).
