The actual insn it's complaining about is: 

(jump_insn 90 89 91 (addr_vec:SI[ 
            (label_ref:SI 33)
            (label_ref:SI 70)
            (label_ref:SI 70)
            (label_ref:SI 36)
            (label_ref:SI 36)
            (label_ref:SI 44)
            (label_ref:SI 65)
        ] ) -1 (nil)
    (nil))

But right off I can't tell if the abort test is wrong, or if the
jump table is supposed to be inside a basic block.

                                               -gavin...

The .i follows for convenience:

# 1 "/sam/gavin/actual-chains/gcc3.x-mips64/src/gcc/testsuite/gcc.c-torture/compile/990801-1.c"
extern int getch();
extern int class();

int
token()
{
    int state = 1;

    while (1) {
	int c=0;
	c = getch();
	switch (state) {
	case 1: break;
	case 4: break;
	case 5: break;
	case 6: 
            {
	        switch (class(c)) {
	        default: break;
	        }
	    } break;
	case 7:	break;
	}
    }
}
