The following program causes an internal compiler error when compiled with
gcc-3.4.3 or gcc-4.0 (CVS):
template <typename T>
class C
{
public:
void foo();
};
template <typename T>
void
C<T>::foo()
{
union {
struct {
};
};
};
int main()
{
return 0;
}

Reduced to:
template <typename T>
void
foo()
{
union { struct { }; };
}
This is invalid code, if we do without template function we get an error:
t.cc: In function ‘void foo()’:
t.cc:8: error: anonymous struct not inside named type
t.cc:8: warning: anonymous union with no members
