That patch was buggy - returning the address of a local variable.
I've attached the corrected version. Same speeds.
BTW, reducing GOMP_SPINCOUNT to 10000 reduces CPU load a lot while
achieving the same speeds. This is because otherwise the threads remain
in active wait during GPU kernel invocations. Unfortunately, the users
won't know to do that for this format specifically.
