With a current snapshot of egcs on i386-unknown-freebsd2.2.6 I do not get
an internal compiler error but the following instead (which still looks
_very_ weird to me)!
x.cc: In function `void bar(struct Foo *)':
x.cc:8: warning: assuming & on `(f->Foo::_vptr$Foo + 8)->__vtbl_ptr_type::__pfn'
x.cc:8: cannot convert `(f->Foo::_vptr$Foo + 8)' from type `const __vtbl_ptr_type *' to type `bool (Foo::*)()'
x.cc:8: warning: assuming pointer to member function is non-virtual
