 That would be a gcc bug.

 However, this initializes all the fields of struct kwinst (there are
 quite a few) and the new code without kw does not. It probably doesn't
 matter, as familykw[] is file-static, but maybe it's better to be
 cautious.
 
 (Does making kw volatile cause the problem to go away?)
