C++ Demangling

[kamlesh kumar]

Hi Devs,

I am looking into this bug
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=84950

I could see that

$cat test
_Q.__0
$c++filt < test
::Q.(void)
$c++filt -v
GNU c++filt (GNU Binutils) 2.30
=================================

With trunk c++filt

$c++filt < test
  _Q.__0
$c++filt -v
GNU c++filt (GNU Binutils) 2.32

I am going through the demangling/mangling docs.
and like to know
which demangled name above is wrong ?

Thanks
