Exit status -1073740791 (0xC0000409) STATUS_STACK_BUFFER_OVERRUN

Smth new.

It's first iGPU task I attempted to run on new device.
stderr, looks quite OK....

Well, it's a classic Windows runtime error - it'll be on the WindowsNT exceptions list. Run outside BOINC and see if you can get a stack trace?

Thanks, Richard!
I'll see if second task fails and then start full-scale troubleshooting as you propose.

It also looks like you are trying to run the intel iGPU at the same time you are running CPU tasks.
Historically that usually slows down the entire system production.

I am speculating here but I wonder if increasing the size of the iGPU buffer might get rid of the error?

Depends on CPU/iGPU performance ratio. For slow GPUs lack of full CPU core can't be compensated by GPU production speedup.
But if GPU just fails - it's counter-productive, indeed.

Probably some ("imprecise" said) too big return type somewhere ? Some issue that would cause only a warning at compile time.

Hi, Urs! So glad to hear from you!!!
Meeting at the end of the world indeed :)

I'm starting to install and configure backup project (Einstein@home for now) on newly revived hosts.
So still don't investigate that error further.
