Subject: [Bug c++/114005] New: Constructing a constexpr std::initializer_list ICEs GCC when using C++ modules
Date: Tue, 20 Feb 2024 01:14:01 +0000 [thread overview]
Message-ID: <bug-114005-4@http.gcc.gnu.org/bugzilla/> (raw)
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=114005
Bug ID: 114005
Summary: Constructing a constexpr std::initializer_list ICEs
GCC when using C++ modules
Product: gcc
Version: 14.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: eddiejnolan at gmail dot com
Target Milestone: ---
Constructing a constexpr std::initializer_list at namespace scope causes an ICE
when attempting to compile this module:
module;
#include <initializer_list>
export module module1;
constexpr std::initializer_list<int> foo{0};
Using the command line:
g++ -g -std=gnu++23 -MD -fmodules-ts -MD -fdeps-format=p1689r5 -x c++ -c
Compiler explorer link: https://godbolt.org/z/6Te44T6oo
Error message:
module1.cpp:5:8: internal compiler error: in tree_node, at cp/module.cc:9320
5 | export module math;
