Subject: Sparse fooled by double semicolon
Date: Tue, 30 Jan 2007 23:50:27 -0500	[thread overview]
Message-ID: <1170219027.11455.68.camel@dv> (raw)

Hello!

I have reduced a spurious sparse message to the following test:

#include <string.h>
void test(void)
{
	struct { int foo;; } val;
	memset(&val, 0, sizeof(val));
}

Running sparse on this code gives:

test.c:5:8: warning: memset with byte count of 0

Replacing two semicolons with one fixes the warning.  That's the current
sparse (006eff06c7adcfb0d06c6fadf6e9b64f0488b2bf) with no local changes.
