Actually, this does look like our bug this time - or at least I've just
identified a bug that could cause this, and we'll fix that.
Can you please try this change:
In opencl_zip_fmt_plug.c, change this line:
cl_uint zero = 0;
to read:
static const cl_uint zero = 0;
then re-run the "make -sj4". Does this help?
You'll still want to also use that "--cost" option I had recommended.
