<pre>Attempting to demangle '_ZTv0_n12_NSt9strstreamD0Ev' results in 'non-virtual
thunk to std::strstream::~strstream()'. However, unless I'm really misreading
the ABI incorrectly, this should be a _virtual_ thunk.
It would appear the culprit is line 4417 of cxa_demangle.cpp -- it should be
looking at first[1], not first[2].</pre>
