  22 <em>Warning:</em> In this release, the GDB commands for type and range
  23 checking are included, but they do not yet have any effect.  This
  24 section documents the intended facilities.

  27    <p>Some languages are designed to guard you against making seemingly common
  28 errors through a series of compile- and run-time checks.  These include
  29 checking the type of arguments to functions and operators, and making
  30 sure mathematical overflows are caught at run time.  Checks such as
  31 these help to ensure a program's correctness once it has been compiled
  32 by eliminating type mismatches, and providing active checks for range
  33 errors when your program is running.
  34
  35    GDB can check for conditions like the above if you wish.
  36 Although GDB does not check the statements in your program, it
  37 can check expressions entered directly into GDB for evaluation via
  38 the <code>print</code> command, for example.  As with the working language,
  39 GDB can also decide whether or not to check automatically based on
  40 your program's source language.  See <a href="Support.html#Support">Supported languages</a>,
  41 for the default settings of supported languages.
