 * CWE: 789 Uncontrolled Memory Allocation
 * BadSource: connect_socket Read data using a connect socket (client side)
 * GoodSource: Small number greater than zero
 * Sinks:
 *    GoodSink: Allocate memory with new [] and check the size of the memory to be allocated
 *    BadSink : Allocate memory with new [], but incorrectly check the size of the memory to be allocated
 * Flow Variant: 14 Control flow: if(global_five==5) and if(global_five!=5)
