--- Comment #1 from Jonathan Wakely <redi at gcc dot gnu.org> ---
Please provide the compiler commands, not just a link to a cmake project on
godbolt, which is a pain to see what it's doing.
Only one file and one command is needed to reproduce this:
export module mod;
template<class T> struct A : T {
constexpr A(T v) : T{v} { }
~A() = default; // Fixes GCC.
};
struct B {
virtual ~B() = default;
};
export inline constexpr auto x = A{B{}};
export constexpr const A<B>* y(const B& b) {
return dynamic_cast<const A<B>*>(&b);
}
$ g++ -std=c++20 mod.cpp -fmodules-ts -c
mod.cpp:1:8: internal compiler error: in tree_node, at cp/module.cc:9078
1 | export module mod;
| ^~~~~~
Please submit a full bug report, with preprocessed source.
See <http://bugzilla.redhat.com/bugzilla> for instructions.
Preprocessed source stored into /tmp/ccYLb5i0.out file, please attach this to
your bugreport.
Maybe a dup of PR 99769 which fails at the same place in a typeid expression.
