Maybe examine the compiler flags, compiler version and CPU running the binary.

I use the symas-packages from repository. I did not compile it on my

This could be the problem:
https://git.symas.net/symas-public/libargon2/-/blob/master/Makefile#L59
:

# Detect compatible platform
ifneq ($(OPTTEST), 0)
    $(info Building without optimizations)
     SRC += src/ref.c
else
    $(info Building with optimizations for $(OPTTARGET))
     CFLAGS += -march=$(OPTTARGET)
     SRC += src/opt.c
endif

What is $(OPTTARGET)? I would be inclined to believe it is _not_
x86_64, which is the amd64 base machine. Instead, $(OPTTARGET) is
using an ISA that is higher than what your XEON provides.

But this is just a guess. A disassembly around ip:7febaf26a415 would confirm it.

kernel: traps: slapd[18020] trap invalid opcode ip:7febaf26a415
sp:7fc3ad4b69e0 error:0 in libargon2.so.1[7febaf266000+5000]

Hi Jeff,



Stefan

this is all Greek to me :-) I'm not a programmer I'm just an administrator, so I'm not in the debugging an disassembly business :-)
