|   void bar() { if (foo()) ; }
| };
| ======================================

| The error message reads:
|   bug.cc: In member function 'void A::bar()':
|   bug.cc:4: error: could not convert '#'obj_type_ref' not supported by
| dump_expr#<expression error>(this)' to 'bool'

I think I crossed this silly behaviour from the error.c several types,
but it was always in a bigger context.  Thanks for reducing it to this
small.  I'll fix it. 

| With GCC 3.4.4 I get
|   bug.cc: In member function `void A::bar()':
|   bug.cc:4: error: could not convert `(**((A*)this)->A::_vptr.A)(((A*)this))' to
| `bool'
| which is better, but not optimal.

Agreed.
