Subject:	RE: [ntdev] How do we create a hardcoded breakpoint?
To prevent from stopping (and BSOD) use macro:

#define DEBUGBREAK() __try { KdBreakPoint(); } \
			__except( EXCEPTION_EXECUTE_HANDLER) {}

So if debugger is present you will stop inside of the __try statement.
If debugger is not present the exception will be handled and execution
will proceed as if there was not a breakpoint.

Regards,

Vladimir
