========================== run mysqld ===========================================
root@NanoPi-K2:/server/bin# mysqld

Illegal instruction

======================= console info ====================== 

20:23:15 UTC - mysqld got signal 4 ;
This could be because you hit a bug. It is also possible that this binary
or one of the libraries it was linked against is corrupt, improperly built,
or misconfigured. This error can also be caused by malfunctioning hardware.
Attempting to collect some information that could help diagnose the problem.
As this is a crash and something is definitely wrong, the information
collection process might fail.

It is possible that mysqld could use up to 
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 6683 K  bytes of memory
Hope that's ok; if not, decrease some variables in the equation.

Thread pointer: 0x0
Attempting backtrace. You can use the following information to find out
where mysqld died. If you see no messages after this, something went
terribly wrong...
stack_bottom = 0 thread_stack 0x3c000
The manual page at http://dev.mysql.com/doc/mysql/en/crashing.html contains
information that should help you find out what is causing the crash.

8.0.13 on support RHEL7 / OL7 distribution works ok (yum distro)
8.0.13 compiles on RHEL7/OL7 without problem (source distro)
8.0.13 compiles on ubuntu and armbian too without problem (source distro)

tested also 5.7 on RHEL/OL 6.3 and it compiles and runs without problem (source distro)

so this is either a toolchain issue or distro issue

kind regards
