Trouble updating to most recent wip (and sigma question)
 
I started out with the below question about sigma(), but I decided to make sure I had the latest and greatest ("Updated to revision 390.") and now I get:
[code]
$ ./yafu
Segmentation fault (core dumped)
[/code]or:
[code]
$ ./yafu "sigma(951452727946218710,1)-951452727946218710"
Segmentation fault (core dumped)
[/code]Header from previous (working) YAFU version:
[code]
09/30/20 08:21:01 v1.35-beta @ math99, System/Build Info:
Using GMP-ECM 7.0.5-dev, Powered by GMP 6.2.0
detected Intel(R) Xeon(R) CPU E5-2620 v2 @ 2.10GHz
detected L1 = 32768 bytes, L2 = 15728640 bytes, CL = 64 bytes
[/code]I tried earlier revisions and 388 and below work, while 389 and 390 crash.


===================================
Original question while YAFU was working:

Is there a way to get just the result from a command line invocation of sigma()?

-silent appears to only suppress empty lines.

With -silent
[code]
$ ./yafu "sigma(951452727946218710,1)-951452727946218710" -silent

[/code]The result isn't returned in either factor.log (not really expected), or session log (expected):

As usual, thanks for your diligent usage and testing. You can try r392 now.

I've tested a few of the basics with
1) NFS=1 USE_AVX2=1 USE_BMI2=1 SKYLAKEX=1
2) NFS=1 USE_AVX2=1
3) NFS=1 USE_SSE41=1

with both gcc 7.3.0 and icc on linux. No crashes so far.

Sigma (indeed, any command), will now return a result into session.log. The .ini initialization is now quieter by default as well.

Thanks much! It is now returning the result in session.log, but I'm only getting r391 and still seeing all the initialization.

Oops, forgot to commit that - should be there now.
