This points to an immediate problem in vn_reference_op_compute_hash:
/* Compute the hash for a reference operand VRO1. */
static hashval_t
vn_reference_op_compute_hash (const vn_reference_op_t vro1)
{
return iterative_hash_expr (vro1-op0, vro1-opcode)
+ iterative_hash_expr (vro1-op1, vro1-opcode);
}
op2 is not hashed (whereas it is on the 4.3 branch).

Subject: Re: [4.4 Regression] STORAGE_ERROR raised compiling s-os_lib.adb
No, it doesn't.
Even if the op isn't hashed, it is still compared for in
vn_reference_op_eq, so at worst the non-hashing will make it compare
more vn_reference_op's than it has to, it shouldn't affect
correctness.
