Happened here on a 486dx also, btw

 Unfortunately the little monster is statically linked.
(text + data over 4MB...)  Anyway this is what i did,

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

int main(int argc, char **argv) {
	if (argc < 1)
		exit(2);
	signal(SIGFPE, SIG_IGN);
	execvp(argv[1], argv+1);
	exit(1);
}

and exec netscape.bin thru it.
