It's a consequence of improved two-stage name-lookup. Since BOGUS is not a dependant name, the parser can see that this is a bug, while parsing the template (a not while instantiating it). As you can see, not only the "[with T = int]" is missing, but also the "compiler_bug.cc:9: instantiated from here" line. There is in fact no value for T when the error message is issued. On the other hand, if I change the code to ------------------------------------------ template void f(T) { T::BOGUS; } int main() { f (1); } ------------------------------------------ the compiler has to wait for the instantiation to be able to see that BOGUS is really bogus. In this case I get: bogus.cc: In function `void f(T) [with T = int]': bogus.cc:2: instantiated from here bogus.cc:1: error: `int' is not an aggregate type which does make sense to me.
