Hello,

I have seen it twice, that boinc has reported a successfull outcome. But stderr output looks like this:

The above doesn't look like an successfull run.
My question is, what happens if two machines with the same bug compute the same workunit?
In a bad case they deliver both the same false result.
And the validation process can't detect it. Is this correct?

Absolutely normal - no error

SETI@Home Informational message -9 result_overflow

Means - the WU is considered too noisy if too many "signals" are found
and after max 30 "signals" of one kind is aborted by purpose/design
by SETI@Home app, not by BOINC

Credit is given for the effort (time, FLOPS) till abort
e.g. if the WU processing is discontinued after 77% -
then about 77% of the credit for the full to-the-end computation is given

If you see this happening in multiple WU's then you probably need to restart. Sometimes the GPU gets glitchy or overheats and starts throwing bad results out. In that case just restart your computer
