Subject: strcpy() bug?

The following program:

#include<stdio.h>
#include<string.h>
int main(void)
{
	char *element1[]={"length","length"};
	
	char element2[2][6];

	char *text = "text";

	strcpy(&element1[0][0], text);
	printf("%s %s\n", &element1[0][0], &element1[1][0]);
	
	strcpy(&element2[0][0], text);
	printf("%s %s\n", &element2[0][0], &element2[1][0]);

	return 0;
}
	
produces the output:

C:\STU>gcc -Wall test.c

C:\STU>go32 a.out
go32 version 1.11.maint3 Copyright (C) 1993 DJ Delorie
text text
text

Whereas if *element1[] is initialised as:
	
	char *element1[]={"length","short"};

the outputs from the two printf() statements are identical. i.e. when
the two strings are the same, strcpy() appears to copy `text' to
&element1[0][0] AND &element1[0][1]. This does not occur with MS and
Borland C.

Any ideas?
