This bug does NOT seem to be GC related! I tried with various different
heap sizes and this didn't make a difference. Given that reduction went
quite smoothly I don't really think that GC plays an important role.

Here's a further reduced test case:
================  cut ========================
struct ios_base {
	virtual ~ios_base() {}
};
struct istrstream : public virtual ios_base
{
	    ~istrstream();
};
istrstream::~istrstream() { }
================  cut ========================

Both virtual keywords are essential, also adding inline to the istream
destructor makes the bug go away.
