From: "waffl3x at protonmail dot com" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug c++/110566] New: [13/14 Regression] ICE when instantiating function template with template template parameter with 2 or more auto parameters with a dependent member template, ICE in tsubst, at cp/pt.cc:16135 Date: Wed, 05 Jul 2023 21:52:07 +0000 [thread overview] Message-ID: <bug-110566-4@http.gcc.gnu.org/bugzilla/> (raw) https://gcc.gnu.org/bugzilla/show_bug.cgi?id=110566 Bug ID: 110566 Summary: [13/14 Regression] ICE when instantiating function template with template template parameter with 2 or more auto parameters with a dependent member template, ICE in tsubst, at cp/pt.cc:16135 Product: gcc Version: 13.1.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c++ Assignee: unassigned at gcc dot gnu.org Reporter: waffl3x at protonmail dot com Target Milestone: --- https://godbolt.org/z/6d4ec5va3 template<template<auto, auto> typename> void takes_templ(); template<typename> struct v_v_member_templ_fn { template<auto, auto> using fn = void; }; using ice = decltype(takes_templ<v_v_member_templ_fn<void>::template fn>()); This one seems kind of boring to me, only interesting things to note are the ICE only manifests with 2 or more (I assume) auto template parameters, it works as expected with only a single auto template parameter. The version of GCC on my local machine that exhibits this behavior is: 13.1.1 20230429 Not as convoluted as I'm used to, but at least that means it should be easy to fix! One can hope anyway.
