Thumbs down LLR4 and PRP3 bugs

PRP3 and the newest LLR(P4) versions are buggy and - under certain circumstances - miss primes!

http://www.mersenneforum.org/showthr...0739#post40739

George is currently fixing PRP3 (see #41 - fortunately, Ivan missed him; hopefully, Jeanne does so, too...).
For the time being, I switch my PC over to sieving until a new version is out.

Chances are the circumstances that lead to errors can be examined, so that only a fraction of the numbers tested by these clients have to be rechecked.

This project is immune to the PRP3 bug. Only 7-9 digit k values are problematic.

The LLRP4 bug might affect this project. Only Jean Penne knows.

As far as i know we have never received results from LLRP4. So we should be save from that side also.

Alright, then I'll restart PRPing. Thanks for that information, George!
