--- Comment #2 from Patrick Palka <ppalka at gcc dot gnu.org> ---
Confirmed, likely started with r13-2351-g33005a4be49466 though it's ultimately
a latent modules bug. Reduced testcase:
$ cat 106826_a.C
export module pr106826;
template<class T> constexpr bool is_lvalue_reference_v = false;
template<class T> constexpr bool is_lvalue_reference_v<T&> = true;
$ cat 106826_b.C
module pr106826;
static_assert(is_lvalue_reference_v<int&>);
$ g++ -fmodules-ts 106826_a.C
$ g++ -fmodules-ts 106826_b.C
106826_b.C:2:15: error: static assertion failed
It looks variable template partial specializations get lost during streaming.
