Summary: Front end issue
Product: gcc
Version: 4.5.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: sla...@codeaurora.org
The following C++ code:
class C {
public:
static int N;
union U {
int m;
char k;
};
typedef void (*A[3])(int);
} c;
int C::N = 0;
int n = 0;
template <class T> struct S {
void f(void) { (void) sizeof(typename T::N); }
};
S<C> s;
void g(void) { s.f(); }
Should compile fine per ISO/IEC 14882:2005, 14.6 (Name resolution). It fails
with plain vanilla x86 4.5.1 release:
g++ -v
Using built-in specs.
