Bug ID: 19495
Summary: Warn about out of scope tests
Product: clang
Version: 3.4
Hardware: PC
OS: Linux
Status: NEW
Severity: enhancement
Priority: P
Component: Static Analyzer
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
Classification: Unclassified
The following program:
static int arr[] = { 1, 2, 3, 4 };
int lookup( int index )
{
if( index<1 || index>4 )
return -1;
return arr[index];
}
Passes the static validator without a warning. This despite the off by one that
makes accessing element 0 impossible, and element 4 out of bounds.
