>Description:
	
	If a user changes has argv[], ps locks up.
	PS. I'm not really sure if this is a bug, or just an annomoly
>How-To-Repeat:

	run the below program, and then run ps xa

#include <stdio.h>
#include <signal.h>

void domore(int);

int max;
char **gargv;

main(int argc, char *argv[])
{
	int i;
	max = 50000;

	gargv = argv;

	signal(SIGBUS, domore);

	for (i=0; i < max; i++)
		gargv[0][i] = 'd';

	printf("found at %d\n", max);

	sleep(10);
}

void
domore(int sig)
{
	int i;
	max--;

	for (i=0; i < max; i++)
		gargv[0][i] = 'd';
}
