Sourcing the following script

  unsetopt errexit
  FOO==ls 2>/dev/null
  echo OK
  FOO==nonexistent 2>/dev/null
  echo OK

produces only one "OK" before the script crashes.  This seems like
a serious bug to me; it makes the =command facility all but useless.
Is there any way around this?

It's not a bug, it's an intentional feature of file expansion.  Try 
"setopt nonomatch".

Or don't use file expansion.  =command was really meant as a shortcut for
interactive command entry, not as a scripting tool.  In a script you 
should be using something like

  FOO=$(whence -p nonexistent)
