Modular debugger for C/C++/D programming languages (and virtually anything else that supports Stabs/DWARF debug formats), Includes Gtkmm-based GUI, and Python scripting framework.
DWARF is supported via libdwarf (see http://reality.sgiweb.org/davea/dwarf.html).
Works on Intel and AMD (32 and 64-bit) processors. Support for PowerPC 32-bit is there but has not been tested in a quite a while.
Platforms such as ARM or Itanium are NOT supported at this time.
Debugging of stripped programs (and especially multi-threaded stripped executables) is not currently supported.
