------- Comment #4 from ciaran dot mccreesh at googlemail dot com 2008-08-27 17:07 ------- I don't expect it to link. I do expect it to compile. In real code I would of course have struct B in a header and template class B<int>; in a different source file.
So far as I can see this is a change in behaviour in 4.4 that goes against both the draft standard and how the GCC extension used to work, and which makes 'extern template' effectively useless. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=37256
