In my version of Turbo C, the following program fails on several memory
models.
/*
 *	This program works correctly on the tiny, small, and medium models,
 *	but fails with the compact, large and huge models.
 */
main() {
	char * junk1, *junk2;
	junk1 = (char *)malloc(1000);
	junk2 = (char *)malloc(1000);	/* Malloc had better return new value*/

	printf("junk1=%p, junk2=%p\n", junk1, junk2);
	printf("%s\n", (junk1 == junk2 ? "OOPS." : "OK."));
}

This program writes OOPS under the circumstances described above.  HOWEVER,
if you include <alloc.h>, then the problem goes away, because malloc isn't
properly declared to return a pointer (32 bits) instead of an int (default).
