Reversible Debugging

[Horace Blegg]

You might consider using a VM with 'save-points'. You run the program (in a
debugger/ida/what have you) to a certain point (logical point would be
if/ifelse/else statements, etc) and save the VM state. Once you've saved,
you continue. If you find the path you've taken isn't what you are after,
you can reload a previous save point and start over, trying a different path
the next time.

This is also somewhat useful if you're trying to debug an error that happens
deep inside of a program, so you can continually jump to the point right
before the error happens, instead of needing to run through the entire
program each time it crashes. Just beware of tunnel vision.
