Argh!  Sorry Kevin, I'd missed that patch, and it isn't in the list of 
posts I'd hung on to (actually, I'd already left for Xmas by that point, 
so it was probably part of the 5000 or so emails I had to skim when I got 
back in January ;-(.

Hmm, it seems substantially the same as mine, but with a couple of minor 
differences.

1)  You don't seem to initialize the pointer fields in the static frame 
structure "prologue_cache".
2)  Similarly you don't seem to be allocating the saved_regs for the 
caller_fi frame (arm_frame_chain).  You do, however, allocate the 
extra_info.
3)  You have a cleanup for the extra_info allocated above, which I hadn't 
thought about.  I think one is also needed for the saved_regs.
