<pre>lit reports the #line 0 warning to be on line 4294967295.
The following test case demonstrates the problem:
****
// RUN: %clang_cc1 -fsyntax-only -verify %s -Wgnu
// expected-warning@+1 {{#line directive with zero argument is a GNU
extension}}
#line 0
****
Note that a test like this:
#line 0 // expected-warning {{#line directive with zero argument is a GNU
extension}}
does not cause a problem.
Also note that clang correctly reports the warning on the relevant line (not 4
in this case).</pre>
