-Shows the module that contains the given address
-
-To debug a problem in AROS, do the following:
-
-1. Get a stacktrace with bt or similar.
-2. Use findaddr with such an address to find out in which
-   module it is:
-3. Use add-symbol-file to load that modules symbols.
-4. Now you can run bt (or similar) again and you should see the
-   addresses resolved as symbols.
-
-Example:
-
-0x4058d45b in ?? ()
-
-(gdb) findaddr 0x4058d45b
-
-Searching in the loaded modules...
-Address found in Workbench:contrib/Zune/Libs/muimaster.library, which is loaded at 0x405379a4.
-If this is an executable, its .text section starts at 0x405379b0.
-(gdb) add-symbol-file contrib/Zune/Libs/muimaster.library 0x405379b0
-add symbol table from file "contrib/Zune/Libs/muimaster.library" at

-(y or n) y
