[Bug libstdc++/42230] New: abi::__cxa_demangle fails to return the length of the decoded name

[gcc at magfr dot user dot lysator dot liu dot se]

When calling abi::__cxa_demangle("e", 0, &length, &cc) length is not updated
but the documentation indicates that it should be set to the length of the
demangled name.

It seems that this change was introduced after 3.4.6
