>Description:
One killer feature would be to be able to change the code being debugged through source recompilation.

IE the following scenario:
* gdb hits a breakpoint, or code causes exception
* examine stack, current calls, incriminated code part
* change your code
* recompile the program
* gdb reloads modified program and goes on executing this modified version

This would really simplify debugging, as sometimes you get obscure errors / make stupid mistakes easy to correct but rerunning the program takes a while, and are glad to "dynamically" change the code being executed/debugged.
