The HP WDB GUI 5.5.2 is a graphical user interface (GUI) designed by Hewlett-Packard for the HP Wildebeest Debugger (WDB). It supports source-level debugging of programs written in HP C, HP aC++, and Fortran 90 on Itanium®-based systems running HP-UX 11i v2 or HP-UX 11i v3, and PA-RISC systems running HP-UX 11.0, HP-UX 11i v1, HP-UX 11i v2, and HP-UX 11i v3. HP WDB is an HP-supported implementation of the Open Source GDB debugger developed by the Free Software Foundation.

This version supports the following features:

• Support for heap check string on/off:

  WDB GUI supports the heap-check string on/off feature of GDB. If the check string flag is set to on, it enables the validation of calls to functions such as strcpy, strncpy, memcpy, memncpy, memmove, memset, bzero and bcopy. The heap-check string on/off option is available from Tools --> Memory Check. When the check string is turned on, memory warnings if any, will be displayed in the command window of WDB GUI.

• Support for display of memory layout for a given address:

  WDB-GUI displays memory contents for a given address. This option is available from the View menu. The contents can be viewed in decimal, hexadecimal, octal, unsigned decimal, binary, float, address, instruction, character and, string format. For a given display format, the contents can be viewed in byte, halfword and word sizes.

• Support for display of a short description for an assembly instruction:

  WDB-GUI displays a brief description of the assembly instruction, when the mouse pointer is hovered over an assembly instruction in the Disassembly view.

• Special key strokes for minimizing and maximizing WDB GUI windows:

  WDB-GUI window can be minimized and maximized with the following hot key combination:

  Key Combination	Function
  Control + Shift + <	Minimizes WDB-GUI window
  Control + Shift + >	Maximizes WDB-GUI window

  Note: These hot keys work on Unix terminals and applications only.

• WDB GUI aborts on reaching the change_mark() function.
• WDB GUI crashes when source window is made invisible and, on loading a file.
