I don't understand exactly what you mean by "it worked correctly". The documentation says: Disable generation of information about every class with virtual functions for use by the C++ runtime type identification features (`dynamic_cast' and `typeid'). If you don't use those parts of the language, you can save some space by using this flag. Note that exception handling uses the same information, but it will generate it as needed. In particular, you cannot use dynamic_cast and -fno-rtti at the same time. So far, it appears to me that your programs were contrary to the documented recommendation. This PR should be closed as invalid. | Is my summary of how it is done using only the vtable inaccurate? As far as I understand the issue, yes. -- Gaby -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=28687
