            Bug ID: 113121
           Summary: <print> failed to load pendings for
                    ‘std::__format::__do_vformat_to’
           Product: gcc
           Version: 14.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: libstdc++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: saifi.khan at nishan dot io
  Target Milestone: ---

built and working with g++ (GCC) 14.0.0 20231222 (experimental).

When I attempt to compile header unit of <print> with the following command

g++ -std=c++23 -v -g3 -fmodules-ts -x c++-system-header print

errors out

/opt/gcc/include/c++/14.0.0/print: In constructor
‘std::basic_format_arg<_Context>::basic_format_arg() [with _Context =
std::basic_format_context<std::__format::_Sink_iter<char>, char>]’:
/opt/gcc/include/c++/14.0.0/print:55:56: error: recursive lazy load
   55 |   vprint_nonunicode(FILE* __stream, string_view __fmt, format_args
__args)
      |                                                        ^~~~~~~~~~~
/opt/gcc/include/c++/14.0.0/print:55:56: fatal error: failed to load pendings
for ‘std::__format::__do_vformat_to’

With an earlier build 20231217, I did not encounter any error while trying to
compile the header unit, instead when i compile test code. Please see

--- Comment #1 from Marek Polacek <mpolacek at gcc dot gnu.org> ---
This works for me:

$ xg++ -std=c++23 -g3 -fmodules-ts -x c++-system-header print -c

Can you please retry now?
