GCC 4.1.2 just to produce just: <source>:3: error: invalid use of 'virtual' in template declaration of 'virtual int S::foo(int)' While GCC 4.4 and above produce: <source>:3: error: templates may not be 'virtual' <source>:3: error: templates may not be 'virtual' So this is a regression even for the C++98 case. ^ permalink raw reply [flat|nested] 6+ messages in thread

Maybe GCC's second error message could be changed to talk about pure virtual and such. ^ permalink raw reply [flat|nested] 6+ messages in thread
