I'm concerned about this, too. One of my next high priorities for godebug is to download many open source projects and search for behavior differences caused by the debugger. I would also like to generate new programs and test them as well.

I will. I'm excited about the project and want to make it as useful as I can.

A compiler transforms source code. It doesn't have access to all programs either, yet we trust them most of the time.
