--- Comment #38 from Mark Wielaard <mark at gcc dot gnu.org> ---
For reference the symbols in comment #4 and the reduced case from comment #14
are fixed by the patch proposed for Bug 78252 - C++ demangler crashes with
infinite recursion with lambda (auto).

The patch proposed for this bug is for generic infinite recursion protection
for symbols like in the original description (or fuzzed ones like in bug
#67264).
