[Bug c++/15427] New: [3.4 regression] valid code results in incomplete type error

[nick at ilm dot com]

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.

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.
