 Hmm, the code is:

00000000        nop
00000000        nop
24861000        addiu   a2,a0,4096
fc800000        sd      zero,0(a0)
fc800008        sd      zero,8(a0)
fc800010        sd      zero,16(a0)
fc800018        sd      zero,24(a0)
24840040        addiu   a0,a0,64
fc80ffe0        sd      zero,-32(a0)

and it obviously cannot work on a MIPS I processor.  That's probably from 
broken assembly code somewhere -- I should have my sources updated within 
a few days and I'll see if I can reproduce the problem.
