(gdb.info) Messages/Warnings

 
 Optional warnings and messages
 ==============================
 
    By default, GDB is silent about its inner workings.  If you are
 running on a slow machine, you may want to use the `set verbose'
 command.  This makes GDB tell you when it does a lengthy internal
 operation, so you will not think it has crashed.
 
    Currently, the messages controlled by `set verbose' are those which
 announce that the symbol table for a source file is being read; see
 `symbol-file' in  Commands to specify files Files.
 
 `set verbose on'
      Enables GDB output of certain informational messages.
 
 `set verbose off'
      Disables GDB output of certain informational messages.
 
 `show verbose'
      Displays whether `set verbose' is on or off.
 
    By default, if GDB encounters bugs in the symbol table of an object
 file, it is silent; but if you are debugging a compiler, you may find
 this information useful ( Errors reading symbol files Symbol
 Errors.).
 
 `set complaints LIMIT'
      Permits GDB to output LIMIT complaints about each type of unusual
      symbols before becoming silent about the problem.  Set LIMIT to
      zero to suppress all complaints; set it to a large number to
      prevent complaints from being suppressed.
 
 `show complaints'
      Displays how many symbol complaints GDB is permitted to produce.
 
    By default, GDB is cautious, and asks what sometimes seems to be a
 lot of stupid questions to confirm certain commands.  For example, if
 you try to run a program which is already running:
 
      (gdb) run
      The program being debugged has been started already.
      Start it from the beginning? (y or n)
 
    If you are willing to unflinchingly face the consequences of your own
 commands, you can disable this "feature":
 
 `set confirm off'
      Disables confirmation requests.
 
 `set confirm on'
      Enables confirmation requests (the default).
 
 `show confirm'
      Displays state of confirmation requests.
