Im currently writing a relatively large program(200k code)
	and I keep getting a page fault error.  I know what it is,
	but not why it's happening, I'd post the code, but the
	relevant portion is about 20k.

	One function is systematically called a user-defined number
	of times by another function.  The called function uses calloc()
	4 or 5 times, in order to allocate 81 bytes/calloc call, and once
        the caller is done, the caller then frees the memory via a global
	variable pointer array.
	The global variable holds 20000 entries, but the program crashes
	after 15800 or so.  The called function also uses sprintf() to
	assign a string to the new memory.

	I have sufficient memory, and have spent too much time on this
	already, does anyone have any thoughts or ideas??
	The program works perfectly as long as the total number of calls
	to calloc() is below 15800, give or take... I haven't tried 
	using malloc instead(my next step), but would much prefer
	to use calloc().

	Im running gcc 2.7.2.1, under DOS 6.22 on a 486DX/40.
