> I have never had such a pleasant bug-reporting experience. Within a day of reporting a new bug, somebody [...] would run the test case and mark the bug as confirmed as well as bisect it using their huge library of precompiled gcc binaries to find the exact revision where the bug was introduced.

That's a really cool setup. Precompiled binaries to quickly git bisect a change.

How often did you run into not being able to use git bisect because you encountered problems due to code changes that were unrelated to the bug you were hunting?

Quickly being able to reproduce and find the commit for a bug is tremendously useful.
