It's good to see Go officially supported.

What happened before? Go documentation was already claiming gdb was the debugger to use.

For anyone, like me, who had no idea what reverse debugging was, you can step backwards from a breakpoint/segfault or whatever. http://sources.redhat.com/gdb/news/reversible.html

Thanks, this is amazing.

I'm not a heavy user of gdb but every now and then I have to pull it out and use the basic features that I learned in a tutorial one day. I can't believe I have never heard of reverse debugging, would have saved a ton of time.

I ran into it accidentally just the other day, but all it told me was that I couldn't use it while debugging a multi-threaded program. I was immediately both elated and disappointed in the feature, since nearly all the C++ programs I work are multi-threaded.

I don't know if that's true in the latest versions, but it certainly seems like solving that problem in a multi-threaded environment would be difficult.

Edit: this seems to indicate it can be enabled in a threaded program: http://stackoverflow.com/questions/7517236/how-do-i-enable-r... I will have to try it. I guess it's just another case of a badly worded error message "Target multi-thread does not support this command." sure makes it sound like you can't reverse in a multi-threaded program, doesn't it?
