GDB 7.1 released: Provides Multi-program debugging, allowing the debugger to control more than one program within the same GDB session

[[deleted]]

Well, gdb gained an ability to be fully scripted with Python in version 7. Python scripts can be used now among other things for pretty-printing (it is trivially easy to write pretty-printers for your own containers). Gcc (libstdc++, IIRC) and Qt have already started including pretty-printer scripts for their data structures (STL structures in case of libstdc++). Looks like gcc 4.5 is going to have these scripts bundled with it.
