the first one .. with a known compiler version and known source code, I
can produce an executable that has the same MD5 checksum (or CRC) as an
executable generated at a previous time by the same compiler and source
code, the option on guessing branch probabilities seems to suggest that
this won't happen for me unless I switch this off and I'm wondering if
there are more options like this that I need to know about,

Dave.
