--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
I'm getting

> ~/install/gcc-12/usr/local/bin/g++ -S t.ii -O  -Werror=maybe-uninitialized
t.ii: In instantiation of 'std::Trans_NS___cxx11_basic_string<_CharT,
<template-parameter-1-2>, <template-parameter-1-3>
>::Trans_NS___cxx11_basic_string() [with _CharT = char; _Traits =
std::char_traits; <template-parameter-1-3> = char]':
t.ii:54:49:   required from here
t.ii:37:37: error: no matching function for call to
'std::Trans_NS___cxx11_basic_string<char>::<unnamed
struct>::._anon_0(std::allocator_traits<std::allocator<char> >::pointer)'
   37 |   Trans_NS___cxx11_basic_string() : _M_dataplus(_M_local_data()) {}
      |                                     ^~~~~~~~~~~~~~~~~~~~~~~~~~~~
t.ii:25:10: note: candidate:
'std::Trans_NS___cxx11_basic_string<char>::<unnamed struct>::<constructor>()'
   25 |   struct {
      |          ^
t.ii:25:10: note:   candidate expects 0 arguments, 1 provided
...

so the testcase doesn't compile for me
