[Bug c++/23156] New: Fails valid? (valid according to Comeau anyway)

[Bug c++/23156] New: Fails valid? (valid according to Comeau anyway)

[igodard at pacbell dot net]

typedef int A;
struct foo{
A A;
};

compiles in 3.4.0 and on Comeau, but on 3.4.2 you get:


changedMeaning.cc:3: error: declaration of `A foo::A'
changedMeaning.cc:1: error: changes meaning of `A' from `typedef int A'

So who's right, you or EDG?

The code is ill-formed; no diagnostic required.  GCC-3.x, x < 4 used to

and fixed later.

Both, but we're better ;-)
