The proof of concept ASCII file for c++filt

Hi There

Our fuzzer generates an input which may hang the execution of c++filt, please
check it on your side if this is a real positive. You could use 
./c++filt < input
to reproduce it.

Originally I reported it to binutils bugzilla, the link is
https://sourceware.org/bugzilla/show_bug.cgi?id=23589, the maintainer confirmed
it is a problem with the C++ name de-mangling code and recommended me to
resubmit here.

Thanks
Peng
