Bug ID: 32911
Summary: false positive report: clang SA falsely assumes that
the loop is executed 0 times
Product: clang
Version: trunk
Hardware: PC
OS: Windows NT
Status: NEW
Severity: enhancement
Priority: P
Component: Static Analyzer
Assignee: kremenek at apple.com
Reporter: daniel.krupp at gmail.com
CC: llvm-bugs at lists.llvm.org
Since clang SA falsely assumes that the loop is executed 0 times
it reports "The left operand of '==' is a garbage value" for the following
code:
static unsigned size = 32;
int init(int *s);
void assert(int);
static void test(void)
{
int val;
if (size>10){
for (unsigned j = 0; j<size+1; j++)
init(&val);
assert((int) (val == 1));//false positive report
}
}
