Of course you use the debugger to debug the core. Doesn't change the fact it's completely unrealistic to expect that you can do that with a full debug build.

Of course you use the debugger to debug the core. Doesn't change the fact it's completely unrealistic to expect that you can do that with a full debug build. The industry has moved towards software as a service, and sometimes your service crashes and you need to figure out why. Even if you want to turn the problem into a regression test that you can run a debug build against, you'll still need to look at the core of the optimized build to figure out what happened to begin with.
