// Dummy is called by the C code before registering the exception/continue handlers simulating a debugger.
// This makes sure that the Go runtime's lastcontinuehandler is reached before the C continue handler and thus,
// validate that it does not crash the program before another handler could take an action.
// The idea here is to reproduce what happens when you attach a debugger to a running program.
// It also simulate the behavior of the .Net debugger, which register its exception/continue handlers lazily.

//export Dummy
