            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: kremenek at apple.com
          Reporter: shachar at shemesh.biz
                CC: llvmbugs at cs.uiuc.edu
    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.
