Bug ID: 60186
Summary: [4.9 Regression] [c++11] ICE with invalid value in
constexpr array initializer
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:
=========================================
template<typename> void foo(int i)
{
constexpr int a[] = { i };
}
=========================================
bug.cc: In function 'void foo(int)':
bug.cc:3:27: internal compiler error: unexpected expression 'i' of kind
implicit_conv_expr
constexpr int a[] = { i };
