by the new prst app. There are some issues with similar CPUs and Riesel Bases (-1), Sierpinski Base is fine:

GenuineIntel Intel(R) Celeron(R) J4125 CPU @ 2.00GHz [Family 6 Model 122 Stepping 8]
GenuineIntel Intel(R) Celeron(R) CPU N3150 @ 1.60GHz [Family 6 Model 76 Stepping 3]
GenuineIntel Intel(R) Pentium(R) Silver J5005 CPU @ 1.50GHz [Family 6 Model 122 Stepping 1]

I am glad it is just GWNUM (or the Intel CPU design itself?) that is at error here, it happened just when I added some extra libraries for multiple and arbitrary precision on my J5005....

BTW: The new Sierpinski Base app runs like a dream on one of my Ryzen 7 5700G machines, kudos.

P.S.: Get well soon!

The gwnum must have a bug, already reported to the dev.

If you have such errors with these CPUs, disable work for -1 bases until this is fixed.

Just a hunch: You do know that these CPU's have a thing in common? No L3 cache. If your code for -1 bases explicitely makes use of L3 cache than they will fail.

This is a recompiled unchanged srbase version with latest code changes and gwnum30.19 for testing for the problem CPUs listed in this thread.

Not sure if this host (Intel(R) Celeron(R) CPU N2940 @ 1.83GHz [Family 6 Model 55 Stepping 8]) was affected but I've run the prst-11-test app and here are the results.

You could try to run prst v10 too so we know it.

Is this as simple as downloading the executable from https://github.com/patnashev/prst/releases/tag/v10.0 and running the same command? I see there's a v10.1 as well.

I downloaded and tried running prst v10.0 and v10.1 from the Github releases however didn't see any output. The "unknown option -boinc" was printed immediately but it continued to run and I left it running overnight but there was nothing printed when I checked it in the morning.

Thanks. Looks like my CPU was not affected. Both 10.0 and 10.1 versions completed fine.

You can run a -1 base on SRBase, to be sure.

Sorry, I'm not sure what you mean. Is this a specific application/ subproject in SRBase?

Thanks, will give it a try when there's work available.
