Alexander,

You are correct, this is different.

Here is the output from the other CRYPTMD5 and CRYPTSHA256.  The cryptsha256 fails for some reason.

/john -test -format:CRYPTMD5OPENCL

OpenCL Device: ATI Radeon HD 5670

build kernel
end build program
DONE

./john -test -format:CRYPTSHA256OPENCL

build kernel
end build program
end init
crypt_all
FAILED (get_hash[0](0))
