Subject: Bug in john-1.7.8-mscash2cuda-0.diff ?

Here's what I did:

1. Downloaded stock john-1.7.8.tar.gz from openwall.
2. Applied the john-1.7.8-mscash2cuda-0.diff to it (patch diff applies
perfectly - no errors)
3. Compiled in /src directory using "make linux-x86-64-cuda" and no errors
during compile - all clean.  nvcc ran fine and compiled mscash2.cu - no
errors.
4. Then do a ./john --format=MSCASH2CUDA --test

I get the following error and then exits:
Benchmarking: MSCASH2CUDA [GPU]... Invalid CUDA device id = 1

I'm Running on 64bit Ubuntu 11.10 but I tested and same things happens on
64bit 10.04 LTS.  Works fine with the mscash patch
(john-1.7.8-mscashcuda-0.diff) but mscash2 patch has this problem when going
to use it after compiling.  To recap, no other diffs were applied - just
stock john-1.7.8.tar.gz + john-1.7.8-mscash2cuda-0.diff applied only.

My system is an Ubuntu 11.10 with a single GTX 480 card.  All other cuda
tools work fine on this system - oclhashcat, CudaMultiforcer, and John 1.7.8
with other cuda diffs applied (ie. allcuda patch and mscash patch).  Only
mscash2 is failing during the test/benchmark.
