The following code: template<class T> struct A { T foo; }; template<class T> struct B { A<int> _squares[2]; }; results in: >/dept/rnd/vendor/gcc-3.4.0/bin/g++ -c testCornerFinder.C testCornerFinder.C:10: error: field `_squares' has incomplete type with gcc-3.4. gcc-3.3 compiles this code correctly. The code also compiles if the [2] is removed. -nick
Confirmed.
Indeed, how surprising. Giovanni, wasn't it you who was working on incomplete type diagnostics? W.
(In reply to comment #2) > Indeed, how surprising. Giovanni, wasn't it you who was working on > incomplete type diagnostics? Yes, but this is unrelated to the work I did.
Working on a fix.
