--- Comment #22 from Desmond Gold <cooky.ykooc922 at gmail dot com> ---
another one:
template <typename>
void foo() {
constexpr int i = [:reflect_constant(5):];
constexpr info f = reflect_constant_array(
std::vector{1, 2, 3}
);
constexpr auto& arr = [:f:];
constexpr auto& arr2 = [:reflect_constant_array(
std::vector{1, 2, 3}
):];
}
void bar() {
constexpr auto& arr = [:reflect_constant_array(
std::vector{1, 2, 3}
):];
}
results in ICE when splicing 'reflect_constant_array(...)' inside template
definition (initializing 'arr2' inside 'foo'):
<source>: In function 'void foo()':
<source>:11:52: internal compiler error: in get_range_elts, at
cp/reflect.cc:355
