Hi djm, good news! when I build without -march=native the binary runs without core dump! I will try to rebuild passing processor specific compiler flag "-march=bdver2" but even the compiler...

./autogen.sh ./configure CFLAGS="-march=bdver2" --with-crypto --with-curl make build competes and gives me an executable however when i run it I still get a core dump: [root@poweredge-miner1 cpuminer]# ./cpuminer -a mtp -o...

I can give you access to the hardware if needed.

so with no -march=native declared I can now mine without the bin core dumping... however its performance is not optimized Step 1 : Compute F(I) and store its T blocks...

it crashes within an hour: [2019-02-22 08:46:16] CPU #44: 0.69 kH/s cleaning stuff Step 1 : Compute F(I) and store its T blocks X[1], X[2], ..., X[T] in the memory...

I have over 16gig. I will try again tonight with your new build. I will let you know how it goes.
