I have been trying to port some stuff that I did at someone else's 
computer (and had working) to my home machine w/Turbo C++.  After
hours of debugging, I found a gotcha.  The bit of code looked
something like:

	typedef struct MENU {...} MENU;

	main()
	{
		MENU *variable;
		...
		function(variable);
		...
	}

	void
	function(MENU *variable)
	{
		printf("variable is at %p\n",variable);
		...
	}

The problem is that I use the turbo debugger to print the value of
variable and it doesn't match the printed value by printf.  Now,
this works fine with other variables.  I really wouldn't care, but
dereferencing "variable" results in a spontaneous reboot.  

I found the same problem with a different program and recompiling
helped.  Not in this case though.  Could this be a memory model
problem (I believe that I'm using the large model everywhere), or
is there a known bug going about?

Thanks.
