No, the tinderbox just uses -O2 (which implies -fno-strict-aliasing).
I highly recommend compiling with -O2, not just for the performance
advantages, and not just for the additional warnings it enables, but
also because of the additional coverage analysis (required for better
optimization) which results in more accurate warnings.
