When I try that (i.e. without structured bindings), the ICE is gone, but I do
get
foo.cpp: In function ‘auto bind_function()’:
foo.cpp:8:10: error: consteval-only expressions are only allowed in a
constant-evaluated context
8 | sink(attrs.rvp);
| ^~~~~
And if I also first copy attrs.rvp to another char (attrs is what I called the
equivalent of the underlying_var), then that compiles.
In other words, the structured bindings version ICEs, the following one errors
like the above:
auto bind_function() {
constexpr auto attrs = extra_attributes{};
sink(attrs.rvp);
}
And this one compiles:
auto bind_function() {
constexpr auto attrs = extra_attributes{};
char rvp = attrs.rvp;
sink(rvp);
}
I'd expect all three versions to work, but if not, then at least to behave the
same.
