I think that the root cause is somewhere near that:
-when i do not use gpu for cuda for some time and then run -test
-fo=pwsafe-cuda format fails self tests - just once, next run 1s later
and I got pass on self test and later it passes too for some good time
-when i run -test, format fails always

I thought that it is caused by lack of cuda_init but even after adding
it problem still remains. I tried to clean buffers at the init, check
for allocation errors and similar often bugs but everything seems to
be ok.
I spent some time on it yesterday, I am able to reproduce this bug by
running -test but it is not so trivial to get the idea what is wrong.
Now I am trying to do step by step reproduction and probably this will
help find the problem.
