Yes. Only this message every time.
What is interesting, it seems that the segfault appears only after all the calculations are done.
For example, I can add “@show CuArrays.collect(y)” after the multiplication and the code will show the array content, but right after it will print the segfault message.
Can it be some inconsistency between the system CUDA v10.1.105 and the one downloaded by CuArrays, v10.2.89?
Can you try running under gdb: gdb --args julia, then run, do your thing in the REPL, and when it crashes execute bt to see if that gives you a better backtrace.
You can move the conversion to the issue tracker, yes.
