Hi Nick,

Sorry for the late reply. I fetched today's CVS and realized that you already
applied patch 3. I now get the following output when compiling on panda1:

Unwind table index '.ARM.exidx' at offset 0xf8 contains 1 entries:

0x0: @0x0
  Compact model 0
  0x00      vsp = vsp + 4
  0x00      vsp = vsp + 4
  0x00      vsp = vsp + 4

The difference in the two outputs is obviously the compact model bit:

--- exc.good.o.hex    2011-12-20 14:54:09.000000000 +0000
+++ exc.bad.o.hex    2011-12-20 14:54:13.000000000 +0000
