Hmm, why is _gfortrani_options being called, it is data as far as I can 
see.
on ppc-darwin from nm, we have:
000452f0 d __gfortrani_options

where d means data section.

Thanks,

r3 contains the first argument passed from read_real (entry value of r26).

Bah, this can't work on a machine with strict alignment.
