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. -- Gaby -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=22238
