The stack overflow poc

Hi There

Peng Li at Baidu X-Lab found a stack overflow bug in c++filt of the latest
binutils code base, I have confirmed it with address sanitizer. Please use the
“c++filt < stack_overflow_input ” to reproduce the bug. If you have any
questions, please let me know. 

Please note that I submitted this error through email to address@hidden,
please ignore the previous one.

Thanks
Peng
