thank you for your quick reply.
But I'm afraid that didn't help at all.

When I tried running the non-patched version on a 32-bit machine it worked fine.
Well "fine" is an exaggeration. Some of the tests produce unclear
outputs, some of the tests must be reconfigured to flash/flash path
instead of /flash. But in general it works ok, on a 32-bit machine.
