Comment #1 on issue 243 by [email protected]: Internal error! Invalid slab class

what exactly were you doing to cause this error? Just starting it, running tests, etc? Does it still happen if you cut -m to 512 or so? Or leave out -I?
-t 40 is also extremely high, as performance tends to degrade after ~6 threads, but that shouldn't cause a crash.
