Any chance you could help with the following error during compilation?
This is under centos 6 and gcc 8.3.1

util.c: In function ‘send_line’:
util.c:1136:15: error: ‘sock’ undeclared (first use in this function); did you mean ‘work’?
      n = send(sock, s + sent, len, 0);
               ^~~~
               work
util.c:1136:15: note: each undeclared identifier is reported only once for each function it appears in

Ooops, that code is supposed to bre turned off in the field. It appears your CPU has some limited AVX512
capabilities, but not enough for my test code. It also shows my test code did not screen properly for
the correct features. But as I said that code should never have been enabled in the release.

A small code edit in avxdefs.h will fix that. Find the follwing code near the bottom of the file and
change "#if 1" to "#if 0". It'll be fixed in the next release.

Code:
#if 1
//////////////////////////////////////////////////
//
//   Compile test.
//
//   Code to test that macros compile.


yeap, that did the trick for me.

Hello,

I'm getting the following since version 3.9.1.1 on a Xeon D-2141I CPU while compiling with gcc 6.3.0 under a debian system
