 Summary of the bug:

 All versions of compiled ffmpeg 5.0 on Ubuntu 20.04 now produce a segfault
 on completion of any file using hevc_nvenc encode.  This does not happen
 in any ffmpeg version before version 5.0.

 Used release 5.0, then updated to release N-106467-ge301a24fa1.  Same
 issue.  Have to revert to a compiled version of 4.4.1 to avoid this error.

 Commands plus gdb and valgrind output are below.  The problem seems to be
 between ffmpeg/hevc_nvenc and the nvidia drivers.  Sample ffmpeg log
 output is attached.
