Subject: [PATCH 2] Fix core dump on anonymous symbol.
Date: Fri, 9 Feb 2007 16:15:40 -0800 [thread overview]
Message-ID: <20070210001540.GA20644@chrisli.org> (raw)
Using the following can generate anonymous symbol without
initializer expression.
return (struct foo) {};
It would be nice if sparse does not crash on it.
