Some of my workunits reported error, so I want to examine what happened.

According to result of this unit, I think there might be something wrong with cuda application, but I'm not sure.

Is anyone have same result like this? Could it be a result of some program bug?

In this case, it is the one running stock and getting what looks like a good result that is actually wrong. He is running Debian with the old 6.4.5 BOINC client. The rest of the wingmen found too many triplets and the WU will probably run through a couple more people before reporting too many errors and be wiped.

The Linux CPU SETI@home Enhanced v6.03 (stock) validated OK against
Windows 7 GPU NVIDIA GeForce GTX 260 (optimized) SETI@home Enhanced Anonymous platform (NVIDIA GPU) - Lunatics Multibeam x38g Preview, Cuda 3.20

( It's known that stock CUDA apps (they are older) are more prone to "-12 error":
SETI@home error -12 Unknown error
cudaAcc_find_triplets erroneously found a triplet twice in find_triplets_kernel

than the Lunatics optimized CUDA apps (actively developed, newer, faster)
)
