--- Comment #4 from Martin Liška <marxin at gcc dot gnu.org> ---
Reduced test-case:
$ cat pr98000.C
struct {
template <typename T> T *operator()(T);
} hb_addressof;
template <typename, typename, typename... Ts> static int _hb_cmp_method(Ts...)
{
return 0;
}
template <typename V, typename K>
inline bool hb_bsearch_impl(K key, V, int compar(void *, void *)) {
V p;
int __trans_tmp_2 = *hb_addressof(key) = compar(&__trans_tmp_2, p);
return false;
}
struct hb_array_t {
int arrayZ;
};
struct hb_sorted_array_t : hb_array_t {
void bsearch() {
hb_bsearch_impl(bsearch_impl_x, &arrayZ, _hb_cmp_method<int, int>);
}
int bsearch_impl_x;
};
template <typename Returned> struct hb_lazy_loader_t {
Returned *operator->();
};
namespace OT {
struct COLR;
}
struct hb_ot_face_t {
hb_lazy_loader_t<OT::COLR> COLR;
};
struct {
hb_ot_face_t table;
} hb_ot_color_glyph_get_layers_face;
namespace OT {
struct IntType {
typedef int wide_type;
operator wide_type();
};
struct UnsizedArrayOf;
struct OffsetTo {
template <typename Base> friend UnsizedArrayOf operator+(Base, OffsetTo);
};
template <typename, bool> using LOffsetTo = OffsetTo;
template <typename Type> using LNNOffsetTo = LOffsetTo<Type, false>;
struct UnsizedArrayOf {
void as_array(int);
};
struct SortedUnsizedArrayOf {
hb_sorted_array_t __trans_tmp_4;
void bsearch() { __trans_tmp_4.bsearch(); }
};

int __trans_tmp_3 = numLayers;

};
} // namespace OT
void hb_ot_color_glyph_get_layers() {
