Sorry, I've been snowed under with work for the last few days, or I would 
have replied before.

The problem is that the definition of LEGITIMIZE_RELOAD_ADDRESS in arm.h 
is inconsistent with the definition of GO_IF_LEGITIMATE_ADDRESS when 
targeting strongarm (actually, any armv4 chip).  This is fixed in the 
current FSF sources, so I will try to dig out a patch when I have some 
time to spare.

This particular problem is almost certainly not related to the level of 
optimization (ie it can probably occur even at -O0), but the circumstances 
for it doing so will normally be different.

No promises, but send me a reminder if I haven't posted a patch by the end 
of the week.
