--- Comment #1 from David Majnemer <david.majnemer at gmail.com> ---
LLVM has not optimized your program into an inconsistent state because calling
malloc is not an observable side effect in and of itself.  If the compiler can
satisfy your use of malloc in a way which doesn't end up calling malloc, that's
ok.

If you did something else with the malloc'd pointer like called
malloc_usable_size (or escaped it through any other mechanism) then that would
be a different story.
