Bug ID: 58511
Summary: [c++0x] ICE using static const member variable in
constexpr
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++0x") triggers an ICE
since GCC 4.8.0 (when inheriting constructors were introduced):
====================================
struct A
{
constexpr A(int, int = i) {}
static const int i;
};
struct B : A
{
using A::A;
};
constexpr B b(0);
====================================
bug.cc:12:16: error: 'constexpr B::B(int)' called in a constant expression
constexpr B b(0);
^
bug.cc:9:12: note: 'constexpr B::B(int)' is not usable as a constexpr function
because:
using A::A;

Confirmed with trunk, I don't see the ICE with 4.8.2.

Maybe just a STRIP_TEMPLATE issue. Looking into it.
