--- Comment #5 from Jonathan Wakely <redi at gcc dot gnu.org> --- The instructions at https://gcc.gnu.org/bugs/ are very explicit about including that information. 15.1.1 is not a release, it's any snapshot between the date of the 15.1.0 release and now, so is not enough to tell us what you're using. That's why we ask for the 'gcc -v' output.
