Bug ID: 108563
Summary: [concepts] ICE (segfault) when requiring
sizeof(variable_tempalate_v<type>)
Product: gcc
Version: 13.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: ldalessandro at gmail dot com
Target Milestone: ---
The following valid code causes an ICE (segfault)
template <class T>
struct foo {
static constexpr int value = 0;
};
template <class T>
inline constexpr int foo_v = foo<T>::value;
static_assert(requires { sizeof(foo_v<int>); });
Workaround is to use `foo<int>::value` instead of the variable template.
