...

Just a general note: you can be sure that mprime is not a trojan, but do you run every program that you just downloaded from the internet under root?! That's not a good thing to do.

Create a user for everyday use. Log as that user. sudo when needed.

The crash may be related to 64 cpus. Wait for George ("Prime95") to answer.
There's probably a certain AffinityScramble2=... string that you could put in the configuration files.

If you put "NumCPUs=32" in local.txt does it crash?
