  21. JS: 
  22. JS: At the risk of stating the obvious, my workstation will probably
  23. JS: dump core because sscanf wants _pointers_ to int_value and
  24. JS: long_int_value, i.e. &int_value.
  25.  
  26. Actually, &unsigned_int_value is required for %x format. Sending in a
  27. pointer to int results in undefined behaviour. (However, this should
  28. not matter unless the compiler explicitly checks for it: such checks
  29. are allowed, however).
