> Hi mmmtoxic,

> Thanks for reporting this problem. Unfortunately the issue is in the
> name demangling code in the libiberty library, which is actually part
> of gcc, rather than the binutils. (It is used in binutils, but not
> maintained here). So please could you report the bug to gcc.

> times before. The underlying issue is that the name mangling format
> allows for infinite recursion, and so it is always possible to
> construct an artificially mangled name that will require an infinite
> amout of stack space in order to demangle properly.
