Bug #: 53909
Summary: internal compiler error: in gimplify_init_ctor_eval,
at gimplify.c:3560
Classification: Unclassified
Product: gcc
Version: 4.6.2
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: [email protected]
ReportedBy: [email protected]
constexpr constructors and multiple inheritance (non-virtual inheritance,
diamond pattern) don't mix; this causes an ICE with gcc 4.6.2 (minimized from
production code):

struct B { };
struct C1 : B { };
struct C2 : B { };
struct A : C1, C2 {
constexpr A(int x) { }
};
int main() {
A a[] = {1, 2, 3};
return 0;
}
