Hi,

This bug is still present in GCC 11.3.0. My use case is using large
std::arrays. NOTE: the problem immediately goes away if the arrays are not
initialized, but naturally we want to always initialize our variables to
prevent accessing uninitialized data:

-std::array<Foo, 1000000> data{};
+std::array<Foo, 1000000> data;
