Can you give us instruction to reproduce the crash?
The following is my reproduction record.
$ cat main.cc
import std;
template <typename T>
consteval auto nsdm_of() {
const auto ctx = std::meta::access_context::current();
return std::define_static_array(std::meta::nonstatic_data_members_of(^^T,
ctx));
}
int main() {
constexpr auto I = nsdm_of<std::vector<int>>();
}
$ g++ -B. -std=c++26 -fmodules -freflection -fmodule-only --compile-std-module
$ g++ -B. -std=c++26 -fmodules main.cc
Seems like we want to reject the import based on a dialect mismatch,
i.e. check flag_reflection in module.cc get_dialect.
Thanks, the new patch make the reflection in dialect with flag_reflection.
Pushed, thanks!
