Virtual destructor bug

[David Mazieres <dm at reeducation-labor dot lcs dot mit dot edu>]

The following program (a slight modification of a program to
demonstrate another bug), triggers an entirely different bug in the
latest version of egcs.  Adding the firtual destructor causes egcs to
fail with this message:

% c++ -c -O egcs-bug.C
egcs-bug.C:21: sorry, not implemented: `namespace_decl' not supported by dump_type
egcs-bug.C: In instantiation of `ihash<element,1>':
egcs-bug.C:21:   instantiated from here
egcs-bug.C:21: conflicting types for `vtable for '
egcs-bug.C:21: previous declaration as `vtable for struct ihash_core<element,1>'

The program compiles with gcc2 and egcs 1.0.3.

Thanks,
David
