I didn't expect magnum would commit this patch after I had called it in

revert it or fix it for non-OpenMP and benchmark on more systems.
I see you're reporting issues with non-OpenMP builds here:
https://github.com/magnumripper/JohnTheRipper/commit/9e27b6b60852c2dc594fb895eab65fdbc38ec7fe
but it makes no sense to try matching any non-OpenMP build issue to any
other patch until the obvious bugs in the "multi-threaded hash table
initialization" commit are fixed (or it is reverted).
FWIW, in an OpenMP-enabled build it works fine for me. ;-) Just
provides arguably too little speedup to be worth it (and might actually
hurt performance on CPUs with turbo, etc.)
