There appears to be a bug in the gcc version 1.35 running on the Sun386i.
I compiled the source that is listed below with

gcc -o add add.c

And when I run add it causes a segmentation violation! As you can see the
program is fairly small.

/*
 *
 */

main()

{
	int *x,*b,*c;
	register int i;

	x = (int*)malloc(sizeof(int)*10);
	b = (int*)malloc(sizeof(int)*10);
	c = (int*)malloc(sizeof(int)*10);

	for ( i = 0; i < 10; i++ )
		x[i] = c[i] + b[i];
/* the following works instead!
 * for (i = 0; i < 10; i++) {
 *	x[i] = c[i];
 *	x[i] += b[i];
 * }
 */

	free(x);
	free(b);
	free(c);
}
