I played with this a bit more and I think the problem is in collect2.
If you add `-Wl,-debug' to the command, then you get diagnostic output
from collect2.  For some reason, it isn't doing the right thing when
when the destructor for X is virtual.  The following will link ok
aside from the undefined references:

struct X { ~X();  };
struct Y { virtual void foo(); };
struct W : public X, public Y { virtual void foo(); };
struct Q : public W { };
void bar() { Q q; }

Collect2 is not producing the proper constructor output when the destructor
for X is virtual.
