Comment #2 on issue 2885 by [email protected]: mksnapshot's output
isn't deterministic
http://code.google.com/p/v8/issues/detail?id=2885
There are basically 2 sources of non-determinism here:
* You have to specify --random-seed=<some_number> to mksnapshot,
otherwise the RandomNumberGenerator constructor will choose some random
seed.
* You have to make sure that ASLR is off for your OS. On Linux this
means you have to issue:
sudo sh -c 'echo 0 > /proc/sys/kernel/randomize_va_space'
before calling mksnapshot (2 is the default value, enabling full
randomization). Note that this is a global setting.
The question is: Do we really want this? I was no big fan of this
randomization stuff, anyway...
