That is the correct question. We get the error message during
template parsing, not during template instantiation (otherwise
the error message would have "[with Power=4]"). So apparently
the compiler thinks that
Self::allow_double_instantiations
is non-dependent and so tries to instantiate the "tester" template
I think this is wrong: if you write it as Self::allow_double_instantiations
it should be dependent, whereas if you write it without the Self:: it
should be non-dependent.
Can someone double check whether this also happens with mainline?
