benchmark crash
Same i78750H Win10 x64 system that crashes or stalls in prime95 v29.5b5 benchmark, also does in prime95 x64 v29.4b8 benchmark after several rounds at 2304k.This system is 2 weeks old.

The real reason to wait is because there is no Gerbicz error checking for repunits other than Mersenne and Wagstaff, so it's better to wait a while until the memory corruption issues with 29.5 beta are definitely ironed out. Although if you restrict to using only one or two cores, there doesn't seem to be a problem. By the way, for everyone else reading this, the (eventual) discovery of a new record base10 repunit prime could certainly grab the public's imagination, and it's easier to explain than Mersenne primes. As in "11 is prime, but 111 = 3 × 37, 11111 = 41 × 271, etc. You have to go up to 19 ones to get the next prime. The largest known (probable) prime of this form has 270,343 ones..." The search for the next one has reached nearly 4 million ones without success. Maybe the Primenet infrastructure could be leveraged to also host Wagstaff or repunit10 sister projects? Just a thought.

So I want to ask again user Prime95: What is the reason for not implementing it for other bases other that +/2? I think the adaptions for other bases should not be too complicated, I derived it myself for base 10. But there might be some specific implementation details that would make it too complicated.
