Bug ID: 58609
Summary: [4.9 Regression] [c++11] ICE with uninitialized
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++11") triggers an ICE
on trunk (since at least GCC 4.9.0 20130920):
===================================
struct A
{
static constexpr int&& i = 0;
};
int j = A::i;
===================================
bug.cc:3:30: error: non-constant in-class initialization invalid for static
member 'A::i'
static constexpr int&& i = 0;
^
bug.cc:3:30: error: (an out of class initialization is required)
