New description:

 I am not sure this is a bug or very strange hardware problem.  When I
 create a blank video with audio using Windows 10, it usually hangs the
 machine. When the machine was still recently at Windows 7 level, it did
 not hang on this. The same command on Linux never hangs. The machine is an
 Intel i7 5820k 3.3ghz not overclocked, Nvidia Geforce GT740, 64gb memory,
 etc.  It does not get overheated from this.  All other more difficult
 ffmpeg runs run flawlessly.  I was looking for a way to turn off
 accelerations to see if something particular was causing the problem.  The
 command is:
 ffmpeg -y -loop 1 -i blank.jpg -i music.wav -vcodec libx264 -r 59.94
 -acodec aac -b:a 384k -t 00:05:00.000 audioonly.m2t
 blank.jpg is just an all black still 1920x1280.  I am using the latest
 versions of ffmpeg, windows and linux (Ubuntu).  Older versions of ffmpeg
 exhibit the same hang. The -t time parameter is usually around 5 minutes
 and matches the length of the music.wav file.  The hang usually happens
 somewhere in the middle of the run.  Sometimes it can do 1 or 2 runs
 before hanging on the 3rd one, but usually hangs on the first run.
