Hi,
The following testcase is simplified from the wvstreams library + extra tests added. It fails with
current 3.4-branch though they are accepted by gcc 3.3.2, icc and Comeau C++.
[gb@n2 gcc]$ ./cc1plus --version
GNU C++ version 3.4.1 20040607 (prerelease) (i686-pc-linux-gnu)
[gb@n2 gcc]$ cat /home/gb/vrac/template2.cpp
// { dg-do compile }
// Simplified testcase from the wvstreams library
template< class K, class D >
struct A {
template< typename T >
struct B { };
struct I {
void f(void) {
A::B<K> k;
}
};
};
// Related tests?
template< typename K >
struct B {
template< int > struct X {};
template< typename T > struct C {};
struct V1 { B::X<0> x; };
struct V2 { B::C<int> c; };
struct V3 { void f() { B::X<0> x; } };
struct V4 { void f() { B::C<int> c; } };
};
[gb@n2 gcc]$ ./cc1plus ~/vrac/template2.cpp
