--- Comment #2 from Sam James <sjames at gcc dot gnu.org> --- Created attachment 59996 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=59996&action=edit bug118234-concat.xz Okay, concatenating all .(adb|ads) into a file then running gnatchop on it to verify works for me to reproduce the bug. Running `gnatchop -gnat2022 bug118234-concat -w` then `gcc-12 -x ada -gnat2022 test_json_buffered_pull_reader.adb -c` should crash.
