I'm not sure what you mean by "the GPU test". If you were using --test without --format (ie, an all-formats test), this is not supported for GPU builds quite yet (it will be fixed in 1.8). Until then, do something like this:

for i in `../run/john --list=formats|grep -Eo '[^, ]+\-opencl'`; do ../run/john -test -fo:$i || echo -e "(that was $i)\n" ; done

But maybe more importantly, the GPU formats have evolved a LOT since Jumbo-7 (if that is what you are using). Try checking out (or download a tarball with) latest "unstable-jumbo" from GitHub, see:
