             Bug #: 13724
           Summary: vector resize: object pointer is null
           Product: clang
           Version: trunk
          Platform: PC
        OS/Version: Windows NT
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: Static Analyzer
        AssignedTo: kremenek at apple.com
        ReportedBy: roland at utk.edu
                CC: llvmbugs at cs.uiuc.edu
    Classification: Unclassified


#include <vector>
class c
{
public:
    void f() {};
};

int main()
{
    std::vector<c> v;
    v.resize(1);
    v[0].f();
    return 0;
}

gives:

test4.cc:12:5: warning: Called C++ object pointer is null
    v[0].f();
    ^~~~

Without the resize the program is incorrect but then no warning is printed.
