I get the following errors, but no crash.

wrong.cpp: In method `void t::selectfunc(int)':
wrong.cpp:27: taking the address of a non-static member function
wrong.cpp:27:   to form a pointer to member function, say `&t::func1'
wrong.cpp:28: taking the address of a non-static member function
wrong.cpp:28:   to form a pointer to member function, say `&t::func2'
wrong.cpp:29: taking the address of a non-static member function
wrong.cpp:29:   to form a pointer to member function, say `&t::func3'
wrong.cpp: In method `void t::multifunc()':
wrong.cpp:35: no matching function for call to `t::funcptr ()'
