I guess what you are seeing is a program stop at an Exception in std.format that is expected to be thrown by std.format unittests. These are compiled into your executable due to the way they are defined as part of a template. The simplest workaround is to sigh and press "Continue". Alternatively, you can disable stopping on exceptions when they are thrown (unhandled exceptions will still be shown). For Mago, that is done by unchecking "D Exceptions" in the Exceptions window (Ctrl+Alt+E). The Visual Studio debugger treats it as a "Win32 Exception", uncheck "D Exception" below that entry. The downside is that the debugger will also not break for exceptions that you want to debug.

That's the same issue, it doesn't matter where std.format is instantiated. Being a template its unittests are still compiled in.
