                    gimplify.c:2977 since r12-6326-ge948436eab818c52
           Product: gcc
           Version: 12.0

  Target Milestone: ---

Seen for a couple of packages (e.g. bstone):

$ cat bstone.ii
class Rgba8;
template <int _Nm> struct __array_traits { typedef Rgba8 _Type[_Nm]; };
template <int _Nm> struct array {
  typename __array_traits<_Nm>::_Type _M_elems;
};
struct Rgba8 {
  char r_;
  Rgba8();
};
using Rgba8Palette = array<6>;
Rgba8Palette hw_default_palette_;
void hw_initialize_palette() { hw_default_palette_ = {}; }

$ g++ bstone.ii -c
bstone.ii: In function 'void hw_initialize_palette()':
bstone.ii:12:55: internal compiler error: in gimplify_var_or_parm_decl, at
gimplify.cc:2985
   12 | void hw_initialize_palette() { hw_default_palette_ = {}; }
