avx2 doesn't work, segmentation fault, sse4 works, ( intel & amd )

tried this on both i7 6700 and ryzen7 1700 both systems with more than 32gb free ram.. compiled from source on ubuntu linux 64 bit,

Using AVX2 core.
Creating plots for nonces 2048 to 4096 (0 GB) using 2 MB memory and 8 threads
Pre-allocating space for file (536870912 bytes)...
Done pre-allocating space.

tested with 1 thread, x threads

• sample with sse : ( -s 2048 -t 8 -n 32768 -m 4096 )

also note that mjminer works with avx2, (~19k nonces/min ) is this project abandoned and mjminer should be used instead ? should the readme be updated for those who are looking for an avx2 plotter ?

Have a nice day , Francesco
