<pre>(This is the first bug report discovered by one of the SARD tests that I'm
integrating)
The attached file, downloaded from the page at:
<a href="https://samate.nist.gov/SARD/view_testcase.php?tID=149064">https://samate.nist.gov/SARD/view_testcase.php?tID=149064</a>
...file url: <a href="https://samate.nist.gov/SARD/testcases/000/149/064/fmt5-good.c">https://samate.nist.gov/SARD/testcases/000/149/064/fmt5-good.c</a>
causes a false positive "format string is not a string literal".
The function in question:
void
test(char *fmt, char *str)
{
printf(fmt, str); /* FIX */
}
Is called with string literals as fmt:
if(userstr[0] == '!')
test("<%s>", userstr);
else
test("[%s]", userstr);
...this may not be visible from a local analysis of `test`, which would cause
the warning.</pre>
