We should try and make it more non deterministic.
Suggested change

| __CPROVER_assume( pxNetworkEndPoints->pxNext != NULL ); | |
| if( nondet_bool() ) | |

| pxNetworkEndPoints->pxNext = ( NetworkEndPoint_t * ) malloc( sizeof( NetworkEndPoint_t ) ); | |
| __CPROVER_assume( pxNetworkEndPoints->pxNext != NULL ); | |
