winedbg allows the same. use the pass command.

UnhandledExceptionFilter will be called when no stack handler (aka 
try/catch blocks) is found (either none exists, are none of them
caught the exception). UnhandledExceptionFilter is a function
to be called by the program from within its exception handler

I suppose it's the address of a try/block handler on the stack
