unexpected excrement

In current SVN, I'm getting 'crap' for every polynomial for 7+374 with c5=510972

randomizing rational coefficient: using piece #1436 of 1474
p = 71.86 bits, sieve = 105.01 bits
coeff 510972 specialq 4115912013 - 4120408568 other 833550 - 1250325
aprogs: 33036 entries, 45548 roots

I am sure this is entirely uninteresting

This was the same problem Jeff had and it was fixed in SVN 564. I just checked with your number and it still works. Please try it.

Thanks.

Ah, sorry; I'd ended up with fifteen copies of the msieve executable which I [i]thought[/i] only differed in the parameter file, but actually they span a range of SVN versions. Retrying with 570M.

However, I had (because I have the stage-1 threshold compiled in as 1e30 for 195-197 digits) totally different poly lines

FYI, I haven't seen any crap lines in my binaries since you made the fix.

Jeff.

I confirm that my results are also entirely excrement-free.

crapaud

This game, first known as [I]crapaud[/I] (a French word meaning "toad" in reference to the original style of play by people crouched over a floor or sidewalk), reportedly owes its modern popularity to street craps... --Wiki
