Bug #: 51707
Summary: [c++11] constexpr constructor cannot initialize const
reference member
Classification: Unclassified
Product: gcc
Version: 4.7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: [email protected]
ReportedBy: [email protected]
====================
struct S {
constexpr S() {}
};
struct T {
constexpr T(S const& s) : s{s} {}
S const& s;
};
constexpr S s {};
constexpr T t { s };
====================
$ g++ -Wall -std=c++11 constexpr_ref_construct.cpp
constexpr_ref_construct.cpp: In constructor ‘constexpr T::T(const S&)’:
constexpr_ref_construct.cpp:6:34: internal compiler error: in
build_data_member_initialization, at cp/semantics.c:5788
Curiously everything works fine if instead of struct S we typedef S to be an
int (or any other intrinsic type).
