BOINC core hangs when there is active CUDA tasks in queue but CUDA anabled GPU removed

Description (last modified by Ageless)

Please, see this thread for full diagnostic of this issue.

In short, BOINC core hangs badly when there are active CUDA tasks (anonymous platform used) but no CUDA GPU. It does this after changing CUDA task status from "suspended" to "waiting to run". BOINC manager then restarts core from prev saved state with CUDA task disabled.

Note, thet BOINC correctly determined that there is no CUDA GPUs in system. Moreover, using <no_gpu> tag leads to exactly the same behavior.

There are some crash dumps in logs files.
