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 bug-binutils@gnu.org, please ignore the previous one.
 
Thanks
Peng

Please report this bug on the gcc bugzilla system here:

  https://gcc.gnu.org/bugzilla/enter_bug.cgi?product=gcc

The bug is in the name demangling functions supplied by
the libiberty library, which is [art of gcc, not the binutils.
