I'm not sure I'll be able to reduce it, btw. it crashes here:

Well, the reduction isn't exactly valid though, given how it defines
std::list/array.
I guess I could retry reduce with
 class RGWSyncTraceManager {   std::list<std::array<std::string, 3> >
admin_commands; public:   int hook_to_admin_command(); };
 int RGWSyncTraceManager::hook_to_admin_command() {   admin_commands = { {
"sync trace show name=search,type=CephString,req=false", "sync trace show
[filter_str]: show current multis
ite tracing information" },                      { "sync trace history
name=search,type=CephString,req=false", "sync trace history [filter_str]: show
history of multisite tracing inf
ormation" },                      { "sync trace active
name=search,type=CephString,req=false", "show active multisite sync entities
information" },                      { "sync trace
 active_short name=search,type=CephString,req=false", "show active multisite
sync entities entries" } };   return 0; }
as forced last few lines.

Slightly better testcase where basic_string, array and list are at least
templates, again -std=c++20:

namespace std {
struct __new_allocator {};
template <typename> using __allocator_base = __new_allocator;
struct allocator : __allocator_base<int> {};
template <class> struct initializer_list {
  void *_M_array;
  decltype(sizeof 0) __rebind;
};
template <typename T>
struct basic_string {
  basic_string(const T *, allocator = allocator());
  ~basic_string();
};
using string = basic_string<char>;
template <typename T>
struct array {
  T _M_elems;
};
template <typename T>
struct list {
  list &operator=(initializer_list<T>);
};
}
struct RGWSyncTraceManager {
  std::list<std::array<std::string>> admin_commands;
  void hook_to_admin_command();
};
void RGWSyncTraceManager::hook_to_admin_command() {
  admin_commands = {{""}, {""}};
}

Even better don't make second initializer_list member __rebind:
namespace std {
struct __new_allocator {};
template <typename> using __allocator_base = __new_allocator;
struct allocator : __allocator_base<int> {};
template <class> struct initializer_list {
  void *_M_array;
  decltype(sizeof 0) _M_len;
};
template <typename T>
struct basic_string {
  basic_string(const T *, allocator = allocator());
  ~basic_string();
};
using string = basic_string<char>;
template <typename T>
struct array {
  T _M_elems;
};
template <typename T>
struct list {
  list &operator=(initializer_list<T>);
};
}
struct RGWSyncTraceManager {
  std::list<std::array<std::string>> admin_commands;
  void hook_to_admin_command();
};
void RGWSyncTraceManager::hook_to_admin_command() {
  admin_commands = {{""}, {""}};
}

Curiously, changing #include <vector> to #include <array> reproduces the ICE:

#include <list>
#include <array>
#include <string>

struct A {
  std::list<std::array<std::string, 3> > stuff;
  void foo();
};
void A::foo() {
  stuff = { { "", "" }, { "", "" } };
}

The cvise testcase changes the allocator parm to by-value, which hits a
different bug than the original.

    c++: allocator temps in list of arrays [PR108773]

    The optimization to reuse the same allocator temporary for all string
    constructor calls was breaking on this testcase, because the temps were
    already in the argument to build_vec_init, and replacing them with
    references to one slot got confused with calls at multiple levels (for the
    initializer_list backing array, and then again for the array member of the
    std::array).  Fixed by reusing the whole TARGET_EXPR instead of pulling out
    the slot; gimplification ensures that it's only initialized once.

    I also moved the check for initializing a std:: class down into the tree
    walk, and handle multiple temps within a single array element
    initialization.

Can confirm that the fix included in fedora gcc-13.0.1-0.7 works and I have now
successfully built ceph in fedora koji.
