The segfault happens because of this lookup (remove_pseudos):
if ((hard_reg = spill_hard_reg[i]) != NULL_RTX)
The array at i = 699 doesn't seem to contain anything valid.
Function 'assign_spill_hard_regs' sets those values:
spill_hard_reg[regno]
= gen_raw_REG (PSEUDO_REGNO_MODE (regno), hard_regno);
However, in this case it never gets to it because of this:
if (! lra_reg_spill_p)
return n;
