G1 barriers use logical operators (xor) on T_OBJECT mixed with T_LONG. The current implementation of logical operations on x86 in C1 doesn't allow for long operands to be on stack. There is a special code in the register allocator that force long arguments in registers. However T_OBJECT can be spilled, and in that case the xor emission will fail.
