Debug builds are worthless for catching issues. How many people actually run them? Perhaps developers run debug builds of individual binaries they're working on when they're trying to repro a bug, but my experience at every company of every size and position in the stack (including the Windows team) is that no one does their general purpose use on a debug build.
Especially in games, it’s common for only the highly optimised release builds to have playable performance.
Yeah, even their integration tests will probably run in opt mode.
