Bug ID: 101181
Summary: ICE when using an alias template
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: webrown.cpp at gmail dot com
Target Milestone: ---
The following program produces "Segmentation fault: 11 signal terminated
program cc1plus" when compiled with flags
-std=c++23 -fmodules-ts -pedantic-errors -O0 -c
using gcc trunk version
(Homebrew GCC HEAD-da13e4e_1) 12.0.0 20210623 (experimental)
template< class T
, bool = requires { typename T::pointer; }
>
struct p { using type = void; };
template< class T >
struct p<T, true> { using type = T::pointer; };
template< class T > using P = typename p<T>::type;
Without the final alias template, all seems well.
