The semantics of how visibility should work with C++ classes and
templates are obscure and probably still not fully pinned down.  There
has been work in each recent gcc release to address this in various
ways.  You neglected to mention which version of gcc you are using.  I
would recommend trying your program with mainline (the future gcc
4.4).  If it does not behave as you expect, file a bug report (see
http://gcc.gnu.org/bugs.html ).  Thanks.
