Is this member function inline?  Did you add some non-inline methods
to the same class?  GCC uses heuristics to emit out-of-line copies of
inline methods: they're only emitted in the translation unit
containing the first non-inline non-abstract member function of the
class.  This assumption is valid because the C++ Standard requires
every non-abstract member function to be defined.
