--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
We completely intentionally don't emit tail calls to noreturn functions, so
that e.g. in case of abort one doesn't need to virtually reconstruct backtrace.
In your case, the interprocedural optimizations determine expr_main_original is
noreturn and so calls it normally (and optimizes away anything after that
call).
