If your system is working with your old kernel I dont think it could be a

My questions would be:
Which CPU do you use ? Have you emerged a new microcode for CPU ?
Example: Intel has disabled avx in some CPUs via microcode update. Now some
applications may throw an illegal instruction ... and your problem description
look like that only some programs have a problem. You could test it by
compiling your old kernel again ... you should have then the same problem with
it (of course you backup your old kernel before).

The config file is not the same but I have played with what has changed
and I don't seem to be able to fix the problem; no boot.
-> cat /proc/cpuinfo
processor : 0
vendor_id : GenuineIntel
cpu family : 6
model : 158
model name : Intel(R) Core(TM) i7-7700HQ CPU @ 2.80GHz
stepping : 9
microcode : 0x84
cpu MHz : 3680.490
cache size : 6144 KB
[snip]
There are 8 cores.
There may have been a microcode emerge from dependencies; I don't emerge
directly. I do agree with you: if I try to recompile the working
kernel it will not boot. However I am not willing to try just right now
and having to troubleshoot a broken system.
Thanks,
