GCC mistakenly identifies a named parameter as a sentinel. Given the following
program, compiling with -Wformat GCC should warn about a missing sentinel on
the line indicated:
#include <stddef.h>
extern void foo (const char *, ...) __attribute__ ((__sentinel__));
void bar (void)
{
foo (NULL); /* missing warning!! */
foo ("hello", NULL); /* clean */
}
When looking for the sentinel, GCC should skip over the named arguments first
before attempting to locate the NULL pointer.
