I think it just needed
-# define OS_CONTEXT_PC(context) context->sc_elr;
+# define OS_CONTEXT_PC(context) context->sc_elr
but I can't test it. I pushed it anyway. Can you test at the latest commit?

Hi Douglas, many thanks for the very fast response, yep that fixed it.

Just one remark - openBSD has zstd.h, libzstd, etc in /usr/local/include or rather /usr/local/lib. out of the box it doesn't find it.
