Thanks for the detailed explanation and the patches.
I can confirm that with them applied program@execute@calls-struct and
program@execute@tail-calls exit with
CL_EXEC_STATUS_ERROR_FOR_EVENTS_IN_WAIT_LIST, so I guess they work
(or rather, fail) as expected.
Feel free to add
"Tested-by: Maciej S. Szmigiero " tag if you wo=
