Re the debate over whether compilers reliably produce identical object
(executable) files:
The measurement and hashing in TCPA/Palladium will probably not be done
on the file itself, but on the executable content that is loaded into
memory. For Palladium it is just the part of the program called
I'm not surprised that most people couldn't produce a matching PGP
executbales - most compilers (irrespective of compiler optimisation
options etc) include a timestamp in the executable.
