Bug ID: 58674
Summary: [4.8/4.9 Regression] [c++11] ICE with template using
declaration
Product: gcc
Version: 4.9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: reichelt at gcc dot gnu.org
The following invalid code snippet (compiled with "-std=c++11") triggers an ICE
since GCC 4.8.0:
====================================
template<int> struct A {};
template<int N> using B = A<N>;
template<typename T> struct C
{
B<T::i> b;
};
struct X
{
static const int i;
};
C<X> c;
====================================
bug.cc: In substitution of 'template<int N> using B = A<N> [with int N =
X::i]':
bug.cc:7:11: required from 'struct C<X>'
bug.cc:15:6: required from here
bug.cc:7:11: error: the value of 'X::i' is not usable in a constant expression
B<T::i> b;
^
bug.cc:12:20: note: 'X::i' was not initialized with a constant expression
static const int i;
^
bug.cc:7:11: note: in template argument for type 'int'
B<T::i> b;
^
