You can compliantly randomize code generation for security purposes, as
is well known --- see e.g.
So, yes, as Uday says, a compiler can be non-deterministic in practice,
even deliberately (and I suspect non-deliberately too).
I haven't seen randomization for the resolution of unspecified
evaluation order in the standard definition of C (or any underspecified
language) yet, as Uday suggests, but I would be surprised if people
working on (applied or theoretical) program verification didn't think of
