Have you ever used git bisect? If so, how did you use it? Did it help you find a problem which would otherwise be difficult to find? Story time, I guess?

4-5 times now. When confronted with more than a hundred commits between latest known working version and the one you've observed the bug (which was not catched by any of the unit tests) it can save some time to find the fishy commit.

In such a case I create a testcase on top to reproduce the bug. Then bisect and for each stage add the testcase, build, run tests. FYI: this only works if all (or at least most) of the commits in the chain are compilable - if you've done a big messy refactoring with several commits breaking the build, bisect can get you only so far.
