>From looking into the RTL:
(insn 16 15 17 (set (mem/f:SI (reg/f:SI 56 virtual-outgoing-args) [0 S4 A32])
        (addressof:SI (reg/v:SI 61) 60 0x400e28dc)) -1 (nil)
    (nil))

61 is not used any more after that function or before it either.

Getting rid of the friend:
(insn 16 15 17 (set (mem/f:SI (reg/f:SI 56 virtual-outgoing-args) [0 S4 A32])
        (reg/v/f:SI 58 [ <anonymous> ])) -1 (nil)
    (nil))
Which is right.  Looks some thing is going wrong because of the friend, maybe another GC 
problem again?
